Windows 7: USB Devices Slow to Detect / Connect / Disconnect

USB Devices Slow to Detect / Connect / Disconnect

I have a problem with USB "hot-swapping" on Windows 7 being so slow it sometimes doesn't even work.

I have a USB MIDI keyboard (Edirol PCR-500). When I switch it off, then switch it back on Windows 7 takes about 5 minutes to send the familiar "new usb device connected" sound and see it. Sometimes it forgets to actually reload it at all, I have to reboot.

I have a similar problem if I "connect / disconnect" from host in VMWare. Any devices I swap to the Virtual Host and then back again go through exactly the same issue (all of them - webcams - pen tablets - hard drives Etc. Etc).

Over time (due to certain issues with nVidia network cards Etc) I think windows 7 may have built up quite a list of redundant usb references in the registry and trawling through them may be whats slowing it down. Thats a guess, but does anyone know where this "residual" list of devices may be so I can trim them down?

Is anyone aware of any other issues which could be causing this to happen. I have three usb hubs / panels on the system, 1. built on to the motherboard, 2. via a cable from the motherboard to a USB expansion card, 3. a couple on the front of the PC (again connected via cables to the motherboard). Motherboard is a ASUS P5NTWS Holywood Trio.

Any help appreciated. It's driving me bonkers.
