The first attempt with that firmware failed with the messages:

Aug  2 19:01:35 compaq kernel: read firmware upload result
Aug  2 19:01:40 compaq kernel: acx: issue_cmd(cmd:ACX1xx_CMD_WAKE) FAILED

Aug  2 19:01:46 compaq kernel: acx_usb: probe of 2-2:1.0 failed with error 1

I guess that fits in with the messages the ACX module would emit when loaded:

On the second attempt, the firmware upload succeeded, but more errors
followed:

The device was reported in iwconfig as:

but didn't work. In particular "iwlist wlan0 scan" failed with the message:

wlan0     Interface doesn't support scanning : Resource temporarily unavailable

(No accompanying kernel message.)

That archive contains several firmware images but none that seems to fit
the device. Specifically, the module asks for tiacx111usbc1B, but the
archive only has tiacx100usb, no tiacx111usb*, and the radio module IDs
(last two characters) for ACX111 include 16, 17 and 19, but not 1B.
Also, http://acx100.sourceforge.net/wiki/Firmware has this not very
encouraging note:
*  The new TNETW1450 (USB 2.0 capable chipset) isn't fully supported by our driver yet (useful support probably available soon). 
   [This is as of Feb. 2006 - still not supported?]

Btw, about two times out of three, after plugging it in, the device even
fails to activate in Mass Storage mode, endlessly reporting:

Aug  2 20:14:05 compaq kernel: usb 2-2: reset high speed USB device using ehci_hcd and address 12
Aug  2 20:14:20 compaq kernel: usb 2-2: device descriptor read/64, error -110

(ie. ETIMEDOUT) and never switching to WLAN mode. Unplugging and plugging
back in a couple of times succeeds eventually.

Anything else I should test?

Thanks,
Tilman
