Dear Charles and Artem,
I've recently bought a new PowerCom Imperial IMD825-AP LCD which
identifies itself as 0x0d9f:0x0004.
At first glance it seems that usbhid-ups driver works fine. But when I
tried to shutdown UPS via DelayBeforeShutdown it started double beeping
every couple seconds for indefinite time (the same problem described by
Vincenzo Colonnella here:
I suppose that recent protocol change affects a protocol specifications
for DelayBeforeShutdown and powercom_shutdown_info methods should be
modified to support 0x0004 devices. But unfortunately the protocol
specifications attached by Alexey Morozov didn't clarify much for me.
My assumption here that PowerCom developers made a new devices with ID
0x0d9f:0x0004 more compatible with USB HID PDC and therefore we do not
need any specific conversions for passed values anymore.
