Hi all, I'm having trouble with my WL-500GD (2.4). I want my ASUS to get data from weather station Watson W-8681, unfortunately this WS is connected via USB as HID device
Hardware identification:

usb 2-8: new low speed USB device using ohci_hcd and address 2
usb 2-8: configuration #1 chosen from 1 choice
hiddev96hidraw0: USB HID v1.00 Device [HID 1941:8021] on usb-0000:00:02.0-8
usb 2-8: New USB device found, idVendor=1941, idProduct=8021
usb 2-8: New USB device strings: Mfr=0, Product=0, SerialNumber=0

I was running trunk version of Openwrt revision 7880, this revision without hid module doesn't recognize station, so I have decided to build new image. I had downloaded the latest trunk version, updated kernel_menuconfig (enable HID and input devices), build and installed new image. Asus now recognizes device. After the device is connected in dmesg i got information, that new HID device was connected.
New nod /dev/usb/hid/hiddev0 is created.
dmesg:

hub.c: new USB device 01:02.0-2.4, assigned address 6
hiddev0: USB HID v1.00 Device [1941:8021] on usb1:6.0

Then I have cross-compiled script for the weather s. – http://meteolinger.lowlevel.cz/tracker ( http://meteolinger.lowlevel.cz/anonsvn/driver/wwsr.c ). 

Mipsel cross compile:
./staging_dir_mipsel/bin/mipsel-linux-uclibc-gcc -I ./staging_dir_mipsel/include/ -I ./staging_dir_mipsel/usr/include/ -L ./staging_dir_mipsel/usr/lib/ -lusb -O2 -Wall wwsr.c -o wwsr

Classic PC compile:
gcc /usr/lib/libusb.so wwsr.c -o wwsr

When is this script launched, on the output they displayed faulty values and the nod /dev/usb/hid/hiddev0 is dropped and does'n exists until the USB device is reconnected.

dmesg errors:

usbdevfs: usb_submit_urb returned -22
usbdevfs: usb_submit_urb returned -22
usbdevfs: usb_submit_urb returned -22
usbdevfs: usb_submit_urb returned -22
usbdevfs: usb_submit_urb returned -22
usbdevfs: usb_submit_urb returned -22
usbdevfs: usb_submit_urb returned -22
usbdevfs: usb_submit_urb returned -22
usbdevfs: usb_submit_urb returned -22
usbdevfs: usb_submit_urb returned -22

Where should be mistake? Thanks in advance for any ideas (and sorry for my bad English – http://www.virtualnipraha.cz/images/flag_cs.jpg) smile

Nobody has an idea how to solve it?

The discussion might have continued from here.
