I use usb controller in Lpc2148. I get example code from keil website in HID class. I need adapt InReport up to 64 byte( InReport[0],InReport[1]....,InReport[64]) for send more data but I donn't good enough in C programming. How can I do? pleas give code. How can I develop application software in the host side. I need Visual Basic 6 thanks you
"Don't I have to configure the endpoint in the usbcfg?"
I don't think so. If there is anything to modify on usbcfg.h, it's USB_EP_EVENT
usbcfg.h #define USB_EP_EVENT 0x0003
This constant works as a mask to the Events Callback function table in usbuser.c Please note, the logical endpoint number (joined IN and OUT) is applied here.
usbuser.c #define P_EP(n) ((USB_EP_EVENT & (1 << (n))) ? USB_EndPoint##n : NULL) /* USB Endpoint Events Callback Pointers */ void (* const USB_P_EP[16]) (DWORD event) = { P_EP(0), P_EP(1), P_EP(2), P_EP(3), P_EP(4), P_EP(5), P_EP(6), P_EP(7), P_EP(8), P_EP(9), P_EP(10), P_EP(11), P_EP(12), P_EP(13), P_EP(14), P_EP(15), };
Fortunately in this case, the USB_EndPoint1 has been already enabled for EP1 IN. Then, no specific modification for EP1 OUT is required.

As we've observed on the sniffer, the enumeration seems to finish successfully. To confirm it, run these tests.
Confirmation of Enumeration a) Windows Device Manager In the USB development, you should often summon up Device Manager. This is a tip to ease the procedure.
1) Copy these two lines to a blank text file, and rename the file to, for example, DevManager.bat (any .bat will do)
set devmgr_show_nonpresent_devices=1 start devmgmt.msc
2) Double click DevManager.bat, and Device Manager comes up.
(Note) When you select 'Show hidden devices' from 'View' menu, you can see all device instances, even if it isn't currently connected. This function is convenient to clean up the device instances for lost devices.
- Under 'Human Interface Device', can you see the device instance for your board? - Does the property window of the instance (double click the instance) show any trouble?
b) USBView (or UVCView) USBView and UVCView are MS tool to show how Windows recognize the USB devices.
The source code of the USBView is included in the WinDDK. C:\WINDDK\3790.1830\src\wdm\usb\usbview\
MS distribute free WinDDK on this page. "Download the Windows Server 2003 SP1 DDK [236 MB ISO file]" www.microsoft.com/.../default.mspx
SiLabs distributes USBView.exe on their KnowledgeBase page. See the right pane of this article for usbview.zip. "VID/PID/Descriptor Recovery" " " www.microsoft.com/.../WDKpkg.mspx
- Can you see the descriptors of your device properly on the USBView screen?
c) USB compliance test The USB compliance test (USBCV) is a good tool to debug the enumeration code, even if you don't apply the USB logo program of USB.org.
USBCV R1.3 www.usb.org/.../
When you run this tool, attach PS/2 mouse to your PC. USB mouse (and keyboard) doesn't work while this tool is running. Laptop PC is a good platform to run this app, because it usually has PS/2 pointing device. Also, a high-speed hub has to be connected between your PC and the device.
- Run Ch9 and HID test on USBCV
Tsuneo I've downloaded the win DDK and also the VC++ 9.0. I tried to compile with VC++ and had no luck. The compiler says it can't compile "enum.c".
Also I've checked the site you posted " is broken. Could you put the software somewhere I can download or tell me in which compiler the software will compile with?
As to the third thest, I don't have a high speed hub so that won't work.
I've done a couple tests maybe this will give you a hint of what might be: On
void USB_EndPoint1 (DWORD event) { switch (event) { case USB_EVT_IN: GetInReport(); IO1SET = 1 << 20; USB_WriteEP(0x81, InReport, sizeof(InReport)); break; case USB_EVT_OUT: IO1SET = 1 << 19; USB_ReadEP(0x01, OutReport); SetOutReport(); break; } })
I wrote code so that it sets leds 19 and 20 if events IN and OUT occur. The led 20 which represents event in is always set but the led 19 event OUT never gets set. So I went back and tried to use only InReport size of 64 and left the OutReport the ogirinal. The keil original code sends value on InReport[1] =0x01 so on my win application I've put a flag to show that it receives. The flag was never set.
I forgot to mention but on item a) of your post I did all the things that you've mentioned and Windows sees my device as a HID and it doesn't say its not working properly or anything of that sort.
I'm not sure but could there be a problem on my win application? It works fine with the keil example, even if I only change the InReport to 64 bytes the outreport still works fine. Im thinking no because its the device that tells the host how its configuration but Im not 100% sure.
Doug.
I've downloaded usbview. Doug
This is what I get on the USBView

I've got the InReport working, the flag I put finally was set ! :D It was a problem with my application.
Now to the OutReport the kit doesn't even get a USB_EVT_OUT. I suppose the problem is also on the win application but I haven't found out what it is. Doug
The output of USBView on your post is fine. It is confirmed that the enumeration finishes successfully.
"I've downloaded the win DDK and also the VC++ 9.0. I tried to compile with VC++ and had no luck."
WinDDK is distributed with its own C compiler.
To compile USBView on WinDDK, 1) Select one of environment which fits to your OS version (Win XP/2k/2k3) - Start button > Development Kits > Windows DDK 3790.1830 > Build Environments > WinXP [/ Win Server 2k3 / Win2k] > Free build - DOS window pops up.
2) Move to usbview directory and build it > cd src\wdm\usb\usbview > build -cZg
It is documented in "Building a Sample Driver" section of WinDDK help.
"As to the third thest, I don't have a high speed hub so that won't work."
I think you have. "USB2.0 hub" is a High-Speed hub :-)
"Now to the OutReport the kit doesn't even get a USB_EVT_OUT. I suppose the problem is also on the win application but I haven't found out what it is."
When you aren't sure which side the problem lies on, the firmware or the host app, look at the USB traffic.
In this case, - Step execute your host app around WriteFile - If you see nothing on the sniffer (or hardware bus analyzer), the host app is the culprit. - If you see expected URB (USB Request Block), but it doesn't finish, the firmware is the culprit.
For this purpose, any software sniffer will do.
I recommend you SourceUSB in my above post, because this (and BusHound) is the only software sniffer which can catch erroneous enumeration process. Other software sniffers fail to show the enumeration process when it doesn't complete. However, once the enumeration finishes, you can use any software sniffer for debug.

Tsuneo the problem is on the win application. To fix that wouldnt In the case I need to write a driver, does anybody have code for an application written in C++ that compiles with Builder C++? It woold save me a lot of time plus I dont know how to write a driver... Thanks for all the help Doug
This HID component is written in Delphi, but also compatible to BCB (Borland C++ Builder).
"Human Interface Device controller suite" by Robert Marquardt www.soft-gems.net/index.php - Compatible with Delphi 4 to 6 and BCB (tested with BCB 6 Trial).
Tsuneo, you wouldn't have another source for an HID driver for windows would you? Cause I've downloaded the source from where you mentioned but had no luck on putting it to work... the website doesn't provide any support, just a forum where Mike Lischke(the owner) posted a how to make it work but that wasn't of any help Regards, Doug
It's not for BCB but VC6, On "The HID Page" by J.Axelson, http://www.lvr.com/hidpage.htm "Usbhidio_vc6" www.lvr.com/.../usbhidio_vc6.zip
As written in the page, you need HID header files (hid.h, hidsdi.h and hid.lib) for above example. It is included in WinDDK.
"DDK - Windows Driver Development Kit" from MS WHDC www.microsoft.com/.../default.mspx Find "Download the Windows Server 2003 SP1 DDK [236 MB ISO file]" link
You'll also find the HID header files from Win2k DDK in this site for the book, "USB Design by Example, 2nd Edition" (Intel press) www.intel.com/.../FromDDK.htm
