USB and my Blackberry
When I connect my Blackberry, using a USB cable, to charge it up, I get an
error message on the Blackberry that says "USB charging current is not sufficient. Verify that your handheld is connected to a powered USB charging source and that the proper USB driver is installed." When I check the device manager, it shows that "the device is working properly". SO, I just don't know what the problem is?? Help?!

SO, I just don't know what the problem is?? Help?! When attached, an USB device is allowed to draw 100 mA only. Then it can request for more but this can be rejected and the message "USB charging current is not sufficient" is quite perfect in this situation. The device works fine but is not charged. The USB ports of the computer and of powered USB hubs should be able to deliver up to 500 mA while passive hubs are limited to (500-100)mA / (number of ports), so a 4 port hub delivers 100 mA per port only and will reject all request for more.

If you are using a hub try a port on the computer itself.
