USB host controllers and Device 12fd 1001 (aincomm awu2000b or IBlitzz BWU613B)

Hello all,

I just got the said device running on kernel 2.6.4 using the "berlios"
driver.

Only, iwconfig always gives me Link Quality 0/0 ; don't know if this
is a small or a big number :)

However, this device (AIN Comm. AWU2000b) should be included into the
device list with the chipset known to be at76c505_rfmd2958 and the
berlios driver known to be working.

For the records, there's a problem with my VIA MVP3 chipset: the USB 
host controller (VIA rev 2 in Windows language, 1106:3038 (rev 02)
in lspci -n) cannot work with that USB stick; even under Windows XP it 
tells me so (error 10 or something along that line).
Under Linux, the firmware cannot be uploaded. Someone with that hardware
combo and more luck please tell me.

Unfortunately, this MVP3 chipset also has a problem with USB2.0 (EHCI)
PCI adapters based on VIA -- using one of them the system locks up 
(freezes); this is not a bug in the 2.6 uhci_hcd driver (which was the 
'good' uhci alternate JE driver in 2.4 times, not the 2.4 "uhci_ucd").
WinXP also locks up; it's also seemingly not a config error since I just 
threw out about all other cards, swapped PCI slots and such).  [ARGH]
So you cannot use this controller with my main board (no VIA USB on
a VIA chipset main board - funny :( ).

I then tried an OPTi OHCI USB host controller. ( PCI device id 0xc861,
chipset Opti 82c861).
The error message "WARNING: OPTi workarounds unavailable" is very
important - using this USB host controller I always had the atmel
driver tell me there were frames from mars and after some network
traffic I needed to Debian-"ifdown wlan0" and "ifup wlan0" to have
another 2 minutes period of wireless networking.

Now I got another two cards one of them being another Opti OHCI 
controller, using a 82c862 chipset.
But I didn't try it - and I won't, I'm sorry. I've been working for days
to get myself a working USB host controller card. I won't touch the
running system again.

And now here is the one out of four tested (and one nontested) USB 
controllers that's actually working:
A NEC PCI controller (USB 2.0, EHCI) with PCI ID 1033:00e0.
(children 1033:0035).
I didn't compile the EHCI stuff in, but EHCI seems to be backwards 
compatible. To get full USB 2.0 I will compile EHCI into the kernel
soon --- however, I'm currently testing it and while writing this
on a remote (via WLAN) machine I'm watching a movie and am scp'ing
some huge file for fun and testing. The controller works like a
charm as UHCI, I'd expect it to also do so as EHCI.

Ah, and while at it: on the other end there's a Sony Vaio laptop,
USB Controller: Intel Corp. 82371AB/EB/MB PIIX4 USB (rev 01),
8086:7112 (rev 01) which worked flawlessly from day one.

Bottom line is: I had a lot of trouble with the sourceforge driver
before I actually understood that it didn't compile under 2.6 anyway.
I didn't find the USB IDs in that driver. I did have a lot of USB
related problems. The Berlios driver compiled and worked out of the
box, it's trustworthy :) Only I was too tired to find my USB ID
in the driver in the first 5 hours. That was my own fault, however.
