I had an MSI PM8M-V motherboard (Intel CPU, Via P4M800 chipset with\nVT-8237R).\n\nI had a problem with this motherboard, the internal USB ports (the 4\nports on the motherboard headers) would only work at USB 1.x speeds,\nwhile the 4 rear ports worked fine in USB 2 mode.\n\nI went round and round with MSI tech support on this one for 2 months,\nwe even replaced the board, but the replacement board had the same\nproblem. We ruled out drivers and USB header to socket cables as\npossible problems. In the end, both I and MSI tech support gave up: we\ncould not resolve the problem. I replaced the PM8M-V board with a Mach\nTech motherboard from Tiger Direct that is almost identical to the\nPM8M-V, even using the same chips (Via P4M800 and VT-8237R) and it\nworked fine, all ports both internal and rear panel worked as USB 2.0\nports. These two motherboards are so similar that I didn't even have to\nreinstall windows, just swap the hard drive with Windows already installed.\n\nMy question is, does anyone else have a PM8M-V board (or experience with\nit), and do you know if you have/had the same issue? Note that the USB\nports did work .... they would only operate as USB 1.x ports, however,\nand if you plugged in a USB 2 device you got the "This device can run\nfaster if ......" popup over the system tray. Also, the measured\ntransfer speeds really were USB 1.x speeds for those ports, while the\nexact same device plugged into a rear USB port worked fine as a USB 2\ndevice at USB 2 speeds.
