Hai all,
I took a usb skeleton driver program from the kernel source code(drivers/usb/usb_skeketen.c) and compiled and inserted in to kernel (2.6.22) and using that module i transfer data from my usb device to the computer in RHEL. But if i tried in a debian distribution (2.6.22.3 kernel)the application program failed and the dmesg shows a warnig that i dont get in RHEL. Also the /proc/bus/usb/devices file shows the information about my device, but 'lsusb'command does't show anything.Following are the different outputs.

*********dmesg output*******************
usb 2-1: new full speed USB device using uhci_hcd and address 2
usb 2-1: configuration #1 chosen from 1 choice
/home/newshabeer/test/mice.c: USB Skeleton device now attached to USBSkel-192

In RHEL after inserting my module i check the /sys directory, from that i got the device number, create device file and using that i transfer data with my device. Is it correct way??

Please anybody can help me........]
