Hello I am a device developer using AT90USB162(ATMEL) in s.korea I am not good at linux and english Anyway, I developed USB device named multi controller(composite device) that have functioned keyboad, mouse, joystick, and generic interface know as event interface Of course I registered Vendor ID of my device at USB org. It is mean to pass USB org My device be recognized in Windows XP, Vista, Windows 7 Moreover, It is good to Operate at windows system without driver file However, Why can't the device be recognized in linux system I tested the device in fedora12, ubuntu9, etc I face same result in linux. It is mean that I have the problem In other words, The device based AT90USB162 is good in windows system meanwhile I have the problem in linux system I checked the device's recognition using dmesg of linux command Bellow My dmesg log [ 1323.040059] usb 2-1: new full speed USB device using uhci_hcd and address 2 [ 1323.269935] usb 2-1: configuration #1 chosen from 1 choice [ 1323.282972] input: NaMoS JOYTION2: Multi Motion Controller as /devices/pci0000:00/0000:00:10.0/usb2/2-1/2-1:1.0/input/input7 [ 1323.304294] generic-usb 0003:1F0D:0201.0004: input,hidraw0: USB HID v1.10 Mouse [NaMoS JOYTION2: Multi Motion Controller] on usb-0000:00:10.0-1/input0 [ 1333.313073] generic-usb 0003:1F0D:0201.0005: timeout initializing reports [ 1333.321196] input: NaMoS JOYTION2: Multi Motion Controller as /devices/pci0000:00/0000:00:10.0/usb2/2-1/2-1:1.1/input/input8 [ 1333.332321] generic-usb 0003:1F0D:0201.0005: input,hidraw1: USB HID v1.10 Joystick [NaMoS JOYTION2: Multi Motion Controller] on usb-0000:00:10.0-1/input1 [ 1368.337113] generic-usb: probe of 0003:1F0D:0201.0006 failed with error -110 [ 1368.337539] usbhid 2-1:1.3: couldn't find an input interrupt endpoint I am wondering that why I meet the error message "probe a fail" in linux Do you know how I can resolve this problem in linux system Do you have Script or driver files for linux system Of course, I confirm http://www.cs.fsu.edu/~baker/devices/lxr/http/ident?i=probe_count // linux source regarding probe fail Is this linux kernel's bug? so How can I do for this problem I am waiting your good reply. Take care from South korea.
