Hello,
SUMMARY: P55 Chipset/USB has issues with UPS' (broken pipe on 3 diff UPS')
WORKAROUND: Buy/use PCI USB card if you want to use nut/connect a UPS.
NOTES: All other USB (non-UPS) devices seem to function without any
problems.

Problem: When I migrated from a DG965WH -> DP55KG motherboard, there were
quite a bit of issues, host still does not reboot without special flags, e.g.
reboot=a, the NIC driver is broken with the in-kernel version (the one on
e1000.sourceforge) fixes that and finally my UPS USB has driver stale
problems, with two issues already relating to the HW/drivers themselves it
would not be unrealistic to speculate that there could be an issue with the
USB chipset/driver with this P55 motherboard.

Tried another APC 1500VA UPS, same problem occurs, different cable/port etc.
Problem appears to be the Intel P55KG / USB Chipset in the way that it
handles usbhid-raw devices as CD/USB sticks/kbd/mouse/etc do not appear to
be affected.
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:

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.

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:

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.
Justin.
