USB card probs

grilli

I installed a usb 2.0 pci card in my pc yesterday and it was recognised and installed by xp. it works fine when i plug in my bb router but if i plug in another device it cuts off my broadband and doesnt recognise the router. is this normal?

you are drawing all the power for these from your motherboard, used to happen on my older machine all the time until I got an external self powered (mains) hub

grilli

any way around it? the only ports on my pc are 1.1 so trying to upgrade to 2.0

Browntoa

not really, you can try a usb 2.0 powered hub on the PCI card but there is no way round the motherboard problem without upgrading that

grilli

what if i disconnect the existing usb 1.1?

Browntoa

no, the limit is on the Max amount of power that the motherboard will let you draw, mine would crash with anything else plugged in apart from the BB modem

Why don't you try leaving your modem plugged into the existing USB 1.1 port and use you new USB 2. PCI card for other devices? I doubt if your modem would benefit from USB 2.

thanks espresso i'll try that tonight and see if it works.

WOuld a new Power Unit help?

If so I would probably consider getting one! My USB 2.0 Card works with some devices, and others not!

I think it's something to do with the power again! Any way to give priority power to my USB 2.0 card, rather than my onboard USB?

Thanks,

Matt.
