Hi, linux-wireless list. My WiFi usb stick[1] is not registered in rt2800usb.c of kernel 3.0.4, but I here report that it works fairly well. There's also problems stated later. I'm not sure if you welcome this kind of report. If not, sorry, and I wonder if you could write so at linux-wireless website. [1] Vendor: Buffalo Model: WLI-UC-GNHP id: 0x0411, 0x0158 At least I can stably connect to an AP. When the module detects the device, dmesg says: phy1 -> rt2x00_set_chip: Info - Chipset detected - rt: 3070, rf: 0005, rev: 0201. Both patching the source and using sysfs "new_id" file [2] work. (OTOH with the linux 2.6.39.3, new_id doesn't work[3], while patching makes the driver support it.) [2] echo "411 158" > /sys/bus/usb/drivers/rt2800usb/new_id [3] Once, the kernel hanged immediately after touching "new_id" file. Another try resulted in stack trace, and modprobe -r rt2800usb never terminated, although the kernel itself continued running. Next let's see the problems: 1. Sometimes, not always, the PC hangs, showing stack trace (thrown to VT12) when you unplug the device. Sometimes only stack trace is shown in dmesg, and kernel continues running. I've attached a stack trace at the end of this message. 2. It's not really a problem for me, but warnings flood dmesg, like this: phy0 -> rt2800_txdone_entry_check: Warning - TX status report missed for queue 2 entry 5 The last number changes each time. It's only when the card is connected to an AP. If there's something I can do, please ask me. I'm subscribing this ML. I've also tried compat-wireless-3.1-rc8-1, but it is quite unstable, breaking at many stages. I'm not sure if I can keep up with changes in RC based versions. Thanks a lot for developing wireless drivers. Teika (Teika kazura)
