I have configured my pc to use cMP as per the recommendations on the site. Implied Minlogon as well. But since last evening, none of the USB ports work. If I connect my USB hdd, it gets powered but does not appear in "My Computer", nor does the wireless mouse work. What has gone wrong???

Read, please, more attentively "Step 4 – disable unused USB hubs & controllers" here http://www.cicsmemoryplayer.com/index.php?n=CMP.07Optimisations. Probably you disabled the necessary usb ports.

No. All USB ports are enabled. When I connect my USB hard disk it powers up, but it does not get recognised in windows. So does the wireless mouse. They worked fine just a day earlier...

If all the USB ports are definitely enabled, you could try re-enabling the Logical Disk Management service (assuming of course you have disabled it) and taking a look at what it reports. If LDM sees the drive but Windows in general doesn't, it's a known Windows bug (that will certainly, definitely be fixed in SP106).
Change the drive letter [Action > All Tasks > Change Drive Letters] and try again. I get this all the time when hooking backup drives in and out of various boxes.
If that doesn't work (and to help retrieve your mouse), go into Device Manager and see if the devices are recognised there. At least until you retrieve the thing, I'd be minded to use a wired mouse.
You should see the drive under Disk drives , the mouse under Mice and other pointing devices and both under Universal Serial Bus controllers .

That's probably why you didn't post a day earlier . . . :)
BTW, have you checked that the HDD works fine on a different computer?? Especially as it's bus-powered, I'd be minded to check. Bus-powered drives can be moody.

Yes the hdd works perfectly fine on my other computers. I will do as u said & post back...
Just connected a USB pendrive to the port ( flash drive). It performs normally, but the USB hdd does not. The USB root hub has reserved only 200ma for each port. Seems too low I guess. Can this be the cause??
