I don't know how to fix this ..

If I leave anything USB in while I reboot ie. external hdd and dvd burner they all get really slow maybe down to usb 1.
Second if I leave my printer,external and usb dvd burner in when I reboot my usb keyboard and mouse lock up and I have to do a hard reboot. It really burns to have to unplug everything but the keyboard and mouse. Anyone else have this problem ?

When booting up ? It's seems even if I unplug a usb HDD as it's restarting it'll still kill me mouse... It's bizarre. Like I just rebooted and left all my usb HDD's connected and my mouse was fine upong reboot but all my drives are super slow, like I said before it's like it down to usb 1.1 . It's either it freezes or the usb devices are slow. But if they are all unplugged except for the keyboard and mouse it's no problems... mest up

Okay I kind of narrowed it down. In profiler I have USB Bus > which is printer , keyboard and mouse that transfers at 12 mb/s also there is USB High-Speed Bus > External HDD and thumbdrive that transfer at up to 480 mb/s.

When I reboot and leave them plugged in the External HDD and Thumbdrive revert the USB bus which only transfers at 12 mb/s.

Why does it do that at startup ? Is there any way to fix that ?

Damn eh, I think there's a few people that have this issue. Thanks for the tips , at least for now I'll just turn off my external and usb burner when I reboot , no biggy I guess.

Well in the system.kext in the info.plist it show 9.5.0 which is correct as I have voodoo 9.5.0 but in the version.plist is shows 9.4.0 , would this affect it ? Also I have nforce4 mobo mcp61

here's the info.plist

Field Note #1 @kocoman 2009-02-04

yes I have this problem too on msi motherboard, even I am using external PCI usb card. have you try plug and unplug the usb keyboard?

Field Note #2 @kocoman 2009-02-05

Check your system logs [with the console application] and see if you have many usb timeouts, or some messages about the BIOS on unable to gain control.

Field Note #3 @kocoman 2009-02-07

Hmm, for that you would need to buy another hub, then plug your keyboard/mouse into it.

its connecting at the lowest common denominator.

Field Note #4 @LawlessPPC 2009-02-08

does your system kext match your kernel and is it sb600 chipset

Field Note #5 @kocoman 2009-02-15

I am using kernel voodoo 9.6.0 and system.kext 9.6.0 and still have usb keyboard/mouse problems in a vanilla install. but I am using mcp51

Field Note #6 @iwantretailmac 2009-07-09

Mcp51 USB

The developers really need to repast the codes for mcp51 motherboard.
There too have a issue in ethernet cards.

I will wait for some news.
