Hi,
I am planning to buy Ulink-2, can i connect ulink-2 by parallel port or serial port, i don't want to open USB socket in my computer.
I am using win2k.
"The ULINK2 USB-JTAG Adapter connects your PC's USB port to your target hardware..." See: http://www.keil.com/emulators/
Also: http://www.keil.com/ulink2/
It's called a "USB-JTAG Adaptor" because it connects to USB!
Why don't you want to use your USB port?
Programmers can copy the source code in USB thumb drives!
Not if it's got a uLink plugged into it, they can't!
That can also be done via the parallel port, serial port, etc...
the USB storage devices are available very cheap. and easy to hide.
Hope you recall the last issue of Microsoft OS source code available on Internet.
Presently I removed the USB devices setting from BIOS and block the socket.
"Installing Locks on the doors preventing from the gentlemens, thiefs can crack any locks".
"the USB storage devices are available very cheap. and easy to hide."
But then the same has always been true of floppy disks!
I beleive there are tools available to secure against such data theft?
Anyhow, back to your original question, "can i connect ulink-2 by parallel port or serial port" - the answer is, clearly, "No!"
So that leaves you with the quandary: which is the bigger risk - your developers stealing your source code, or your developers being under-productive due to inadequate tools.
Your culture may well be different, but it would certainly demotivate developers over here to be treated as untrustworthy thieves...
"Installing Locks on the doors preventing from the gentlemens, thiefs can crack any locks"
In other words, locks merely inconvenience the honest, everyday user without really detering the thief.
Sad, but true.
:-(
So, what is your point here?
It says to me that all this locking of USB ports is not really going to prevent data theft, but it is certainly going to hamper your development!
Only you can work out the risk/benefit tradeoff in your particular environment...
You can, of course, use uLink for debugging & flash programming without access to the source code.
Again, only you can evaluate the tradeoff in loss of productivity without source-level debugging, and possible motivation issues, against the risk of source code theft...
thanks for your comments.
I found the solution on microsoft to disable only external usb drives. :)
