russian roulette: F5D7051 dongle

Post by sailah »

Hello,

I have this issue with Belqin (F5D7051) wifi dongle based on broadcom 4320 chip in Mint 13 64bit (3.2.0-23-generic) that it works after booting machine or it doesn't and I have to do one or more reboots. I believe the proper driver is rndis_wlan. My suggestion is udevd loads modules asynchronously and therefore this russian roulette behaviour depending on what loads first. Perhaps blacklisting something would help. Please give me some advice where to start? When it loads correctly it works perfectly so the solution should be simple and strightforward !?

lsusb -v (when WIFI)

The difference I see is that module rt2500usb is 'used by':
1 (no WIFI)
0 (WIFI)

Am I right to think that it means that when no WIFI present rt2500usb is used by deamon (according to /etc/passwd) presumably udevd? And it shouldn't be so has to be blacklisted?? Or do I have it completely wrong?


Also when no WIFI present than /var/log/syslog is being updated every second with 2 udevd timeout messages:

Small update: I have installed Mint 14 on a different partition. About 20 times in a row the system booted up with WIFI so I thought something has been improved, but then I had a boot without WIFI and exactly the same symptoms. The only improvement is a little icon form net manager showing WIFI connection when present - that hasn't worked properly in M13. Otherwie the mechanism for loading modules/drivers must have stayed the same. Any thoughts anyone????
