USB Power issues with GL6110.


#1

Hi, I noticed a power supply issue with GL6110. It seems to draw a lot of power, sometimes, if there is another USB device attached to the PC, the modem will not work properly.

The specs says: SUPPLY VOLTAGE 4,75V to 32V DC input, [2A peak/4,75V, 3mA Idle]

2A is a lot of USB power! If i need to connect 16 modems, what is the power requirement for the USB hub i need? Thanks. :smiley:

Thanks for replying, I found the solution, just use an externally powered USB hub.
