HELP……….
Two USB ports @ the back of my tower…….one is used for my ADSL modem, which function correctly………Ive tried to use the other usb port for my webcam………..recently reformatted my HDD & reinstalled the software for my cam…..this worked fine until i tried to use it & my PC froze!!!!!!!!!If i unplug the cam usb connector my ADSL modem works……
If i unplug the ADSL modem usb connector the cam works……So wot the hell is going on here?
Any ideas or suggestions will b gladly appreciated :D
Cheers
It is quite likely that both USB ports run directly from the mother board and share power provided by it (500ma I think). Chances are that the webcam AND the ADSL modem together are taking a load greater than 500ma so they won’t both work at the same time. In essence one gobbles up a large chunk of the available power and doesn’t leave enough for the second device.
Changing the Motherboard is expensive, so why not pop into PC World or similar and buy a USB card. Belkin are generally the best ones and you can get them with 2 or 4 USB ports. These cards take their power directly from the PSU (through one of the MB card slots) so they wil deliver 500ma PER PORT.
Cheers :D
Now u come to mention the power aspect (0.5A) the power to the modem does disappear. Which in turn has a adverse affect on the motherboard causing it to slow down/freeze.Thx again…..ill keep u posted

On the same theme, and for the benefit of any other users, I came across an issue a while ago . When you run an ADSL modem from an USB port running directly off the motherboard and which therefore takes it power from the Motherboard’s power supply, sometimes your PC freezes on boot up or the PC boots but won’t fully go into Windows. You get a screen freeze.
The reason is that the ADSL modem is initiated and starts to take its power from the USB port (i.e. motherboard) at the same time that Windows needs this power to complete the boot sequence. You can boot into Windows if you unplug the modem first and then plug it back in once Windows has loaded, but this is an inconvenient workaround.
Again as above, the fix is to buy an USB card and instal it into one of the spare card slots on the motherboard and connect the modem etc to the USB ports on the card.
You can still use the motherboard based USB ports for plug-n-play items that do not initiate and take power when Windows boots up – digital cameras for example – and keep the ‘new’ USB ports for your ADSL modem etc etc.
Problem solved :D
Thx for ur help & advice
