USB MGE UPS problem

[Daniel O'Connor]

Hi,
I am trying to use an MGE Pulsar Extreme UPS with the NUT port using the 
newhidups driver.

I can read the values just fine but I can't set anything which precludes the 
PC from shutting the UPS off (or in fact configuring it in any way). The 
error is...

...
Looking up DelayBeforeStartup
usb_control_msg: 161 1 791 0 0x514f34 8 4000

USB error: error sending control message: Input/output error

Shutoff command failed (setting ondelay)
...

This program uses libusb to talk to the UPS over ugen - the system has 6.0 on 
it and libusb 0.1.12 (the latest).

I am going to try instrumenting ugen next and see why it's returning EIO.

I checked CVS but I don't believe any of the commits since 6.0 would have an 
effect here.

Does anyone have any suggestions?

Thanks.
