    I have the same card (TL-WN422G)

    Code:
    $ lsusb -d 0cf3:1006
    Bus 002 Device 003: ID 0cf3:1006 Atheros Communications, Inc.
    using kubuntu/ubuntu 9.10 and followed your instructions
    • installed linux-ckports-modules-2.6.31-14-generic
    • sudo modprobe -i zd1211rw
    • echo "0cf3 1006 FFFFFFFF FFFFFFFF 0 0 1" | sudo tee -a /sys/bus/usb/drivers/zd1211rw/new_id


    Since I plugged the usb stick, dmesg showed
    Code:
    [  130.152120] usb 2-3: new high speed USB device using ehci_hcd and address 3
    [  130.301235] usb 2-3: configuration #1 chosen from 1 choice

    [  897.597060] CE: hpet increasing min_delta_ns to 15000 nsec
    Running iwconfig doesn't show my new card. It does, however, show the old card that stopped working a month ago.

    Unfortunately, I can find very little information on this card and driver, beyond what I've already suggested.

    You might give it a go with ndiswrapper instead.

    I'll try, but i don't have ideal experience with ndiswrapper.

    Am i correct that
    Code:
    [  182.481239] usb 2-3: read over firmware interface failed: -110
    means the zd1211rw driver tried to take care of the device?

    -110 means probably -ETIMEDOUT but it makes no sense to me. This is not related to loading firmware from disk, is it?

    Yes, it looks like the driver was recognized and paired with the device. This device also requires extra firmware, which Ubuntu provides.
    zd1211rw - Linux Wireless

    This seems similar to your problem.
    Nabble - zd1211-devs - PN15G firmware upload problems

    This is about the only reference I could find to "read over firmware..." It's the patch to the driver and includes that error output. Perhaps someone with more knowledge of code can better decipher the problem.
    Code:
    +/* Read data from device address space using "firmware interface" which does
    + * not require firmware to be loaded. */
    +int zd_usb_read_fw(struct zd_usb *usb, zd_addr_t addr, u8 *data, u16 len)
    +{
    +       int r;
    +       struct usb_device *udev = zd_usb_to_usbdev(usb);
    +
    +       r = usb_control_msg(udev, usb_rcvctrlpipe(udev, 0),
    +               USB_REQ_FIRMWARE_READ_DATA, USB_DIR_IN | 0x40, addr, 0,
    +               data, len, 5000);
    +       if (r < 0) {
    +               dev_err(&udev->dev,
    +                       "read over firmware interface failed: %d\n", r);
    +               return r;
    +       } else if (r != len) {
    +               dev_err(&udev->dev,
    +                       "incomplete read over firmware interface: %d/%d\n",
    +                       r, len);
    +               return -EIO;
    +       }
    +
    +       return 0;
    [PATCH] zd1211rw: Defer firmware load until first ifup

    You may also be able to build the old zd1211 driver. All the info I could find on it is pretty out of date though. (Which makes sense, as it was discontinued and the community developed zd1211rw took over.)

    Can it be recognized only because i did beforwards:
    Code:
    echo "0cf3 1006 FFFFFFFF FFFFFFFF 0 0 1" | sudo tee -a /sys/bus/usb/drivers/zd1211rw/new_id
    ?

    I also found zd_usb_read_fw function myself (this lead me to -ETIMEDOUT), but does not give me a clue, what does it means, what really happens. Should I enable kernel debugging? Will it give more information in dmesg?
    (In /boot/config-2.6.31-14-generic (presumably the config for my current 2.6.31-14-generic ubuntu kernel) there is CONFIG_DEBUG_KERNEL=y.)

    The patch "[PATCH] zd1211rw: Defer firmware load until first ifup" was included in kernel v2.6.23-rc1, and it's naturally also in my kernel (tag 'Ubuntu-2.6.31-14.48' in Ubuntu kernel repo).

    I don't have any direct experience with this card and I simply cannot find any useful information on the web.

    I encourage you to file a bug report, probably with the upstream developers over Ubuntu.
    Download - Linux Wireless

    You could try other distros, and see if they work better.

    Or unfortunately, you may be stuck with ndiswrapper. It really isn't too hard to use.
    There is a GUI front end called ndisgtk as well.

    Thank you for all the help. A while ago I started discussion on linux-wireless mailing list (at kernel.org; search for 0cf3:1006 or WN422G in the archives) and they suggested

    If you take a look at the vendor's windows driver for TP-LINK WN422G *v2*,
    it becomes obvious that the device does not use the ZyDAS zd1211/ Atheros
    5007UG cipset, but has switched to the new Atheros AR9271 chipset
    [...]
    At this moment a new driver called ath9k_htc is under (early) development:
    wireless.kernel.org/en/users/Drivers/ath9k_htc
    I haven't checked the windows drivers yet, so can't confirm i have "v2". Anyway I won't be copying the list here any further, so i encourage anyone interested in my story (or just having similar device to digg the linux-wireless recent archives.


    As to the ndiswrapper. I know it's not hard, I have already used it on different machine with different card. Maybe it's due to particular windows driver in use, but i see way too often oopses with 'ndis' somewhere in the stacktrace

    That's good to know. Everything I could find on this card suggested it was still zd1211.

    I don't normally suggest ndiswrapper, but I couldn't find an alternative. And I guess that's why - it hasn't been released.

    Thanks for the heads up!
