Hello all,
I'm trying to interface an RFID-tag reader to the Fox, and have trouble with
the USB connection.

The model I have is the IDBlock-RA from EuroChip (more info can be found here:
http://www.eurochip.com/4/sistemi/idblock/info.htm).

It's USB interface is the USB/UART converter CP2101 from Silabs, and  
since it's
driver is included in the 2.6 kernels, I'd expect it to work - in  
fact, my host
machine just sees the reader when I plug it on the bus.

I've compiled the kernel enabling cp2101.ko as a module and loaded it  
on a Fox;
when I plug in the reader, dmesg shows me a few errors, reports that  
the device
is connected as /dev/ttyUSB0, then disconnects it almost immediately and start
doing this again and again. Has anybody tried that driver and know it's
stability?

I suspect that my problem could be a power issue - the docs says my reader
requires a 400mA current, and while my PC provides it on the USB bus, I don't
know if the Fox is able to do the same. Any hints on this issue, too?

Thanks a lot in advance,

Antonio
