Had anyone any success with this usb wireless in recent snapshots.
Following some hints that this chip is not properly powered from USB
port, I hardwired it to the power supply of the computer, but the
result is the same: it fails to load the firmware.
Nevertheless I had some interesting results using some custom usb
cable prepared for some measurements. After a few plug-in actions, the
500mA fuse of my multimeter was destroyed. It looks like there is a
current spike at plug-in time, greater thatn 500mA.
But, switching to a bigger scale and moving the usb wireless module on
another OS, I got aprox. 130mA current draw in a working state.
I tried to recompile the 5.9 release kernel with some added delays in
the code, but I got some errors like syscal 114 and another numbers at
boot time.
