This data is usually given in the device descriptor. The current varies
from device to device. But I have come across drives of 85mA and 100mA.
However some devices have more than 100mA.
The device descriptor of one such device is in the below link.

The above device says the current consumption is 200mA.

Dear All,
What is the worst case current consumption of a USB pen drive from 5V
USB bus across various memory capacities?
Most of the links over th web says its 500mA max.
Please throw in your thoughts.
Cheers
Vivek
