Description of problem:
When I plug in the USB cable of the MGE Ellipse USBS uninterruptible power supply, it fails to give me a USB serial port. Error message from dmesg:
usb 5-1: new low speed USB device using uhci_hcd and address 3
usbhid: probe of 5-1:1.0 failed with error -5
I can also confirm this bug on FC3 with latest kernel (2.6.12 something).
The NUT folks seem to think that configuring CONFIG_USB_LONG_TIMEOUT solves this (see: http://www.networkupstools.org/faq/). Alas, that option doesn't exist anymore.
UPS can be found by NUT just fine when using a serial cable. However, we bought these specifically because of the USB capability, as we need our serial ports for other things.
