Looks like it is a common issue with Windows 8.
Try this if you have it installed:
Both the tdrpm251.sys and the snapman.sys are Acronis drivers, components of Acronis True Image.
These two drivers appear to be from 2009 so may not be fully compatible with Windows 8.
Can you uninstall Acronis True Image and see if the crashes resolve.

The solution that worked was to move the mouse cursor to lower left corner of the screen and rightclick.
Select Command Prompt (Admin)
in the cmd window enter:
and press enter.
After about 15 minutes (about 4 minutes to verify and then just over 11 minutes of waiting while it worked in the background - though it seemed frozen. My system is an i7, 16Gb Ram, 512Gb SSD drive - so your time will vary), I got a message that some corrupted files had been repaired and some had not. The log was in a txt file in C:\Windows\Logs\CBS though the logfile was inaccessable. I got an Access Denied popup.
I restarted the system and everything was fine and the USB problem was corrected.
You should also try turning off power management for your USB HUB devices within the Device Manager. Just right click the USB HUB devices and go to the power management tab. Turn it off and retest.
If you fix the problem would you please post exactly what worked?
