Hi,
I'm using the uvision3 with the Ulink device to debug my programs. But I've got one annoying problem, I connect the Ulink to my laptop and it works fine while debugging but without any reason sometimes it stops working and windows send a message of usb device unknown.
Sometimes the problem is solved by put in out the device and reconnecting it, but sometimes I need to reset my laptop.
Somebody has had the same problem?, how I could solve it?
I have a hunch - and it is nothing more than a hunch - that there may be some sort of conflict between the uLink and (certain) other USB (HID) devices; see: http://www.keil.com/forum/docs/thread14502.asp
