We got a ARM-USB-TINY board recently...
As I wasted half of my day figuring out, the Windows driver .inf and .ini files that come with the ARM-USB-TINY, and that come with OpenOCD downloads have a PID (ProductID) of 3 but they should be 4 for the Tiny board.
There are several places that this must be changed. However, once I got all those fixed both the jtag and serial driver installed.
[Still trying to get code download and debugging going to my SAM7-64. Problem at present is that examples seem to be targeted at the 256k device instead of the 64k.]
From Linux lsusb:
idVendor = 0x15ba
idProduct = 0x0004
iProduct = 'Olimex OpenOCD JTAG Tiny'
I didn't notice any threads that showed a resolution to this problem, so I'm posting a new thread.
