Ultra ULT31502 And Linux

zer0python · 01-26-2006, 10:55 PM

I just invested in a UPS, for my workstation system, and according to the manual it should be compatable with linux, but I have not gotten anywhere as far as getting it to work with linux.. how are various outputs of different programs..

Code:

jaguar ~ # lsusb -t
Bus#  5
`-Dev#   1 Vendor 0x0000 Product 0x0000
Bus#  4
`-Dev#   1 Vendor 0x0000 Product 0x0000
  `-Dev#   3 Vendor 0x0d9f Product 0x0001

`-Dev#   1 Vendor 0x0000 Product 0x0000

`-Dev#   1 Vendor 0x0000 Product 0x0000
jaguar ~ # upsdrvctl start

tcgetattr(/dev/usb/hiddev0): Invalid argument

jaguar ~ #

I also appear to get a lot of these in dmesg:
usb 4-2: usbfs: USBDEVFS_CONTROL failed cmd lsusb rqt 128 rq 6 len 256 ret -110

The default software appears to have been made for serial input; I tried using usbserial, but that didn't work at all.. Any help with this would be much appreciated. -- If you need anymore information just ask.

Okay so I'm guessing that your UPS connects to the computer via a USB connector that emulates a serial port. You could use the lsusb -v command as root to see if your computer hardware detects this device.

Another helpful utility to display hardware that is detected by Linux is hwinfo. I recommend directing the output to a file and then using less to read it. This utility displays a huge amount of detail about your hardware as seen from Linux.

hwinfo > hwinfo.txt
less hwinfo.txt

the output of "lsusb -v -d 0x0d9f:0x0001" is this:

as for hwinfo, it appears to be masked, and probably because I'm running an Athlon 64. Anyway, I'm not exactly sure what do with this information.
