My usb keyboard and mouse stop working for abt 30 sec or so when I put my phone in charging mode with one of my usb ports...will it be safer to get a usb sound card or an internal pci sound card?.I prefer the usb sound card for its portability;especially if I shift to notebook platform. but I am worried about not getting enough juice through the usb port to power the sound amplifier since I have connected quite a number of devices on existing usb ports.. choices are either,'asus xonar DG' internal pci sound card or 'creative sound blaster play 2 usb sound card'.
