Hi
I use a Linux debian 64 bit system. I get the error -71 in the dmesg output, when I plug in the usb2can adapter.
[343375.574269] usb 1-1: new full-speed USB device number 19 using xhci_hcd [343375.694321] usb 1-1: device descriptor read/64, error -71 [343375.944043] usb 1-1: New USB device found, idVendor=0483, idProduct=1234 [343375.944051] usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [343375.944057] usb 1-1: Product: USB2CAN converter [343375.944062] usb 1-1: Manufacturer: edevices [343375.944067] usb 1-1: SerialNumber: ED000200 [343375.951259] usb_8dev 1-1:1.0 can0: firmware: 1.7, hardware: 1.0

Can somebody help?

My usb2can works fine on the same hardware within a virtual Windows XP!

Wrong device descriptor. Does you get similar error in DFU mode too ?

How can I get in the DFU mode?
It is solved: I have no error on a USB-hub!
