Threaded View

strange thing, for the first time I installed a usb Vodafone (K4505)
on a desktop PC (never had problems with laptops), perfect connection,
but ... after a reboot, I inserted the key and all USB ports was
deactivated, included the one for the key (ie key wasn't read)

The desktop PC has Windows 7 x64, 4 GB RAM, 600 W alimentatoe, Quad
Core, etc.

Any ideas?

thank you very much

I don't know if this is the same model of USB device, but they
seem to have a power problem with it. It draws a lot of
current. One suggestion, is not to use it with a long USB
extension cord. Another possibility, is to use a self powered
USB2 hub with its own +5V power supply. Or use any other
means at your disposal, to ensure it is getting enough power.

Apparently, if the signal it is receiving is weak, it'll
increase transmit power, and that makes it get hot, draw
more current and so on. Make sure you're in a location
with good receive signal level, so the device doesn't have to
crank its transmitter power level.

strange thing, the Vodafone USB key (K4505) inserted into a medium-
high level desktop PC - no problems on laptops - with windows 7 x64, 4
gb ram, 600w power supply, quad-core 2.4 GHz causes problems with
other USB ports, making them unstable or off.
Even the port used by the key Vodafone is not read, ie it isn't
mounted as a removable disk.

Connected to other usb ports there are mouse, keyboard and printer.

Any ideas?
