Hey guys I got my Pod hd500 to stop giving me the bsod while using it with reaper by making a new power option on my laptop with windows 8.1.

Go onto this link and look under "7. change power options" and following the windows 8 instructions on making a better power option. I guess turning off the selective usb suspend helped solve the problem. Make sure all your drivers are updated before hand. I hope this helps solve your guys' problem as it solved mine.
