Description Markku Kolkka 2002-08-07 17:52:43 UTC 
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.1) Gecko/20020804

Description of problem:
When I connect the USB cable from my APC BackUPS ES500, the device is detected
but apparently hotplug thinks it's a joystick not an UPS, and as a result the
hidups driver from nut can't open /dev/usb/hiddev0.

Version-Release number of selected component (if applicable):
hotplug-2002_04_01-9

How reproducible:
Always

Steps to Reproduce:
1.Connect USB cable from UPS
2.hidups /dev/usb/hiddev0 (or service ups start)
3.
	

Actual Results:  /var/log/messages shows:
Aug  7 16:25:50 212-246-156-101 kernel: hub.c: USB new device connect on bus2/3,
assigned device number 2
Aug  7 16:25:50 212-246-156-101 kernel: hiddev0: USB HID v1.00 Joystick
[American Power Conversion Back-UPS ES/CyberFort 500 FW: 4.1.I USB FW: d1] on
usb2:2.0
Aug  7 16:25:53 212-246-156-101 /etc/hotplug/usb.agent: Setup hid for USB
product 51d/2/100

hidups fails with:
hiddev open /dev/usb/hiddev0: Permission denied

Expected Results:  The UPS becomes available as /dev/usb/hiddev0, hiddev and nut
works.

Comment 2 Trond Eivind Glomsrxd 2002-08-08 21:13:50 UTC 
Which modules are loaded on the system? It looks like only hid, in which case
hotplug is doing its thing alright... note that read permissions on the device
for non-root users is a separate issue.
Comment 3 Markku Kolkka 2002-08-08 21:21:43 UTC 
_root_ gets the "permission denied" error! If hotplug works correctly, is this a
bug in nut?

Comment 4 Trond Eivind Glomsrxd 2002-08-08 23:10:20 UTC 
OK, so this is not a hotplug issue. Could check if root can read or if nut just
tries to access it as another user?
Comment 5 Markku Kolkka 2002-08-09 10:01:10 UTC 
hidups runs as "nobody", so I must give world read/write rights to
/dev/usb/hiddev0 (bad idea). I'm closing this as NOTABUG.
