NOTES: All other USB (non-UPS) devices seem to function without any problems.

So far all other USB devices work fine, with the exception of UPS', I have tested two APC 1500VA (one an RS the other an XS), in addition I also have a 'BELKIN 1200VA UPS with AVR' from a long time ago, the same problem occurs. Results: - 3 different UPS models (APC 1500VA RS/XS & Belkin 1200VA) - 2 different manufacturers (APC/Belkin) - no other USB devices have problems (tried usb sticks,read cd/dvd, etc) Output from Belkin UPS test: Full update... Can't retrieve Report 7: Broken pipe upsdrv_updateinfo... Got to reconnect! Got 1 HID objects... Full update... upsdrv_updateinfo... Got 1 HID objects... Quick update... Signal 2: exiting BTW, other USB devices are OK, dd'd two USB sticks and a Knoppix DVD on a USB CD/DVD burner with no USB errors/issues. # dd if=/dev/sr0 of=/x/knoppix.iso 8685248+0 records in 8685248+0 records out 4446846976 bytes (4.4 GB) copied, 287.585 s, 15.5 MB/s Given the prior problems with this board (noted at the top, reboot=a, e1000e, etc)- is it possible that Intel needs to provide a BIOS update to fix this or does the USB UHCI driver need an update due to a possible? quirk in this chipset / usb chip? I also tested nut-2.2.2 from Debian Stable and the same problem occurred. A bit frustrated, I popped in a PCI card with 4 external USBs, and now no more errors: Got 11 HID objects...

USB 2.0 (rev 63) It now works fine, using the PCI USB card. However, this P55 board has 12-14 USB ports, it would be nice to use them.
