548930 2007-05-11 03:54:00 Can a computer have two versions of USB ports? (Possibly a dumb question!). I believe that the front two USB ports on my HP Pavillion 1760a are USB 2.0 and I suspect that the four ports at the back are only USB 1.1. When I check my Device Manager Settings I see the following:

Generic USB Hub
Intel(R) 82801FB/FBM USB Universal Host Controller - 2658
Intel(R) 82801FB/FBM USB Universal Host Controller - 2659
Intel(R) 82801FB/FBM USB Universal Host Controller - 265A
Intel(R) 82801FB/FBM USB Universal Host Controller - 265B
Intel(R) 82801FB/FBM USB Enhanced Universal Host Controller - 265C

Only if it had a PCI usb card in it that was one or the other.

The ports on the back are built in to the motherboard so are whatever that board supports.
The front ones are too, because its just a cable from them that connects into the motherboard./

548932 2007-05-11 04:19:00 yes it can but it's not all that common. a simple test is to plug a USB2 flash drive or any USB2 storage device into the ports one at a time. Under XP you get a message along the lines of "this device can operate faster" when you plug a USB2 device into a USB1 / 1.1 port. Also you could try copying a file to and from the pc on different ports to confirm there's no speed difference.

Looks to me like you have 8 USB 2 ports (usually 2 per controller) 2 on front, 4 at the back and possibly another 2 available on the motherboard.

548933 2007-05-11 04:27:00 I have tried plugging a USB 2.0 web camera into both the front and back ports. When it was plugged into the back I got a message similar to that which you described, Dugimodo. Not so when I used the front port. That was what made me suspicious in the first place. lloydallan (11827)

548935 2007-05-11 05:31:00 No I have made no changes to the PC - it is nearly 3 years old. I note that just below one of the USB ports at the front it states USB 2.0 - nothing on the back ports. lloydallan (11827)
548936 2007-05-11 07:12:00 It could be that HP assumed that you would use two USB ports for a keyboard and a mouse, so they could save a small amount of money on those ports. Keyboards and mouses don't need USB2, unless you're a very fast typist. But the mix is wrong for that theory: 2 fast, four slow.

Of course it could have been the well known, and popular, technical process known as the "cockup". I

t's nice that the two front ports are fast so you can plug in portable devices without grovelling around at the back, though I would still prefer to plug a keyboard and mouse into sockets on the front of the box. :(

548937 2007-05-11 10:06:00 Many thanks for your replies. looks like I have two different sets of USB ports somehow. lloydallan (11827)
548938 2007-05-11 13:23:00 you could always google the specs for your pc - HP keep info on their website for quite a long time dugimodo (138)
548939 2007-05-11 19:22:00 Plug a USB2 Hub in the front or add a 4 port USB2 add on card Tony.br (4018)
