You are right. Power coming out of a USB port connected to the PC [as opposed to an unpowered hub] is way lower than the power from the BB USB charger. So charge times from a PC USB port is way slower than from the charger.
Sometimes USB ports on a PC have power fluctuations just as power coming from outlets. At times when I connect my Pearl to a PC USB port I get the error message. I simply disconnect and reconnect the cable. Sometimes I have to reboot. Other times I just ignore the message since I am using DeskTop manager and my intent is not to charge the phone via the PC USB port.
And yes, sometimes it's a matter of the driver from the BB disc not being installed on the PC. Could also be the port is defective on the PC, for any number of reasons, including driver issues.
IMHO USB ports are pretty crappy technology. They are not precision made and there are no manufacturing standards which has resulted in billions of defective or under-performing ports residing on PC's everywhere.
E.g., I have three Dell desktops that I use at the office. On each there are 6 USB ports. On each, about two to three do not work. They are 2004 machines, so they are getting way old, but one would think the USB ports would still work. Maybe I got a bad run of USB ports Dell used that year.
