blue_led, wouldn't it be profitable, to write how correct order of doing things should look, using Your script? I mean executing it before/after connecting device physically, etc. I think it would save us plentora of false bug reports/"it doesn't work for me" posts.

As for script itself, I got strange results testing it with my low-speed USB keyboard, connected to high-speed hub. It result in connecting hub at full-speed (I'm 100% sure hub is high-speed), but I'm not rising alarm, until I get opportunity to check it with another female-female adaptor (loose connection may be the case here). In HEN, sometimes full/low-speed tolerates loose cables, while high doesn't...

I'm waiting eagerly for other reports, cause I've lost hope for new GUI released by MAG.
