[Thinkpad] High Power USB Port

[RWM]

By design, a bare USB port provides 500mA.

I use a 100Gb 7k USB drive that requires 600mA starting current, which 
I've found only works reliably with the Thinkpad via a cardbus PCMCIA 
USB port that supplies 1.0A.  This setup also has a DIN plug that 
supplies power from the Ultrabase.

I've also seen USB drives that require supplementary 5V wall wart power.
