Hi, The usb device driver I wrote, gets registered but it doesn't probe when I plug in the device. I'm not sure about the vendor and product id. the messages i can see with dmesg are: usb 1-1.2: new full speed USB device using uhci_hcd and address 8 usb 1-1.2: device descriptor read/64, error -71 usb 1-1.2: device descriptor read/64, error -71 usb 1-1.2: new full speed USB device using uhci_hcd and address 9 usb 1-1.2: device descriptor read/64, error -71 usb 1-1.2: device descriptor read/64, error -71 usb 1-1.2: new full speed USB device using uhci_hcd and address 10 usb 1-1.2: device not accepting address 10, error -71 usb 1-1.2: new full speed USB device using uhci_hcd and address 11 usb 1-1.2: device not accepting address 11, error -71 how can i get the vendor and product id. any ideas?
