Hi I've posted a question on the gnupic list but it was suggested that I post here to get specialist usb help, so apologies for any duplicates.
I'm trying out a known working pic firmware app and using essentially identical hardware. When I try to connect the device via usb to my fedora core 4 (latest yums) I get the following appearing on dmesg: usb 2-2: new low speed USB device using uhci_hcd and address 13 usb 2-2: device descriptor read/64, error -71 usb 2-2: device descriptor read/64, error -71 usb 2-2: new low speed USB device using uhci_hcd and address 14 usb 2-2: device descriptor read/64, error -71 usb 2-2:

I've used usb_ch9.h and usbmon.txt to try to unpack the log and it seems that the problem may lie in the first two lines. Should you get the C line appearing first? Also, I think I read somewhere that the status 115 should never be seen, but I could be wrong.
