I get a USB system freeze, which does not affect the rest of the system, when I connect my Scanner and initiate SCANdal, and do some scanning.
Which means if I was to then disconnect my printer I would not get it to show up on the system again, unless I reboot, as a USB "Restart" does not fix this issue, it just locks up the entire MOS system if I click in the USB prefs to initiate a USB "Restart" and then I have to warm reboot there and then.
Wheras leaving it alone, even though the printer and scanner or whatever hardware is disconnected the system will carry on until whichever next piece of USB connected hardware is disconnected.
I presume it could be a piece of hardware drawing more power from the USB circuit than it has been 'trusted' to do, but it could be a software issue, as it only seems to happen after I have connected/used my Epson 1640SU scanner through SCANdal.
This information may not relate to your problem, but I thought I would offer it as a suggestion as to the cause - what's the harm.
