MemberOk, so I followed that thread about how to ‘tweak’ the NC10 to make it run faster, and I appreciate all the advice. However ever since I did it I’ve encountered two problems. One was about the volume control (which I subsuquently fixed) and the second (which I haven’t been able to fix) concerns the USB ports.
Before I tweaked the system, I was able to plug in my USB cord to my external CD/DVD writer and ipod, and I had no problems. Now when I plug in the USB cord and try to connect it to something, it doesn’t read it all.
Any advice? As always I appreciate the help. Thanks.

MemberMake sure you haven’t disabled any USB host controllers in Device Manager. If so, re-enable them and your USB ports will work again.

MemberI just checked. None of them are disabled…

MemberDoes this problem occur on just one USB port or all of them? And is it only when using your iPod and drive? Do other devices function as normal on those ports, a mouse for example?
I wonder if perhaps you’ve disabled a service that is required for the USB port(s) to operate correctly or has something to do with disk recognition and management. Could you perhaps go through Freddy’s tweaking guide again and double-check that you adjusted the right services?

MemberUSB Selective Suspend settings fubarred?
Quote:Selective suspend is disabled for upgrade versions of Microsoft Windows XP. It is enabled for clean installations of Windows XP and all installations of Windows Vista.To enable selective suspend support for a given root hub and its child devices, select the checkbox on the Power Management tab for the USB root hub in Device Manager.
Alternatively, you can enable or disable selective suspend by setting the value of HcDisableSelectiveSuspend under the software key of the USB port driver. A value of 1 disables selective suspend. A value of 0 enables selective suspend.
For instance, the following lines in Usbport.inf disable selective suspend for a Hydra OHCI controller:
[OHCI_NOSS.AddReg.NT]
HKR,,”HcDisableSelectiveSuspend”,0x00010001,1Client drivers should not try to determine whether selective suspend is enabled before sending idle requests. They should submit idle requests whenever the device is idle.
