Tested the driver today with that Gembird UIR-22. It did not compile neither in 2.6.30.1 nor in 2.6.31-rc8 with the following error: ark3116new.c:790: error: unknown field shutdown specified in initializer ark3116new/ark3116new.c:790: warning: initialization from incompatible pointer type Commenting that line produced a module that worked: usb 1-1: new full speed USB device using uhci_hcd and address 2 usb 1-1: configuration #0 chosen from 1 choice usb 1-1: config 0 descriptor?? usbcore: registered new interface driver usbserial usbserial: USB Serial Driver core USB Serial support registered for ARK3116 RS232/IrDA ark3116new 1-1:0.0: ARK3116 RS232/IrDA converter detected usb 1-1: ark3116new using IrDA mode usb 1-1: ARK3116 RS232/IrDA converter now attached to ttyUSB0 usbcore: registered new interface driver ark3116new ark3116new:v0.1:USB ARK3116 serial/IrDA driver usb 1-1: ark3116new don't know how to do software flow control NET: Registered protocol family 23 Ran "irattach /dev/ttyUSB0 -s" and then "obexftp -i -l" to list files on Nokia 6230i. It worked fine and file transfer too. So the IrDA mode works. When I unplugged the device, irattach remained running and some error message was written to console every few seconds (sorry, I haven't recorded it). Killing irattach then resulted in oops. But this might be expected as the shutdown function was commented out. I think that this driver should replace current ark3116 driver. Having two drivers for the same hardware is a bad thing. -- Ondrej Zary -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
