[Nut-upsuser] Unitek Alpha 650 ipE

[Andrej Podzimek]

Hello everyone,

has anyone ever tried to make this device work with Linux and NUT?

This is what udevadm monitor says:

	UEVENT[1215983089.652345] add      /devices/pci0000:00/0000:00:0f.2/usb1/1-1 (usb)
	UEVENT[1215983089.652427] add      /class/usb_endpoint/usbdev1.4_ep00 (usb_endpoint)
	UEVENT[1215983089.657975] add      /devices/pci0000:00/0000:00:0f.2/usb1/1-1/1-1:1.0 (usb)
	UDEV  [1215983089.663928] add      /devices/pci0000:00/0000:00:0f.2/usb1/1-1 (usb)
	UEVENT[1215983089.665007] add      /class/input/input4 (input)
	UDEV  [1215983089.666893] add      /class/usb_endpoint/usbdev1.4_ep00 (usb_endpoint)
	UEVENT[1215983089.687097] add      /class/input/input4/event2 (input)
	UEVENT[1215983089.687426] add      /class/hidraw/hidraw0 (hidraw)
	UEVENT[1215983089.688045] add      /class/usb_endpoint/usbdev1.4_ep81 (usb_endpoint)
	UDEV  [1215983089.688161] add      /class/hidraw/hidraw0 (hidraw)
	UDEV  [1215983089.710476] add      /devices/pci0000:00/0000:00:0f.2/usb1/1-1/1-1:1.0 (usb)
	UDEV  [1215983089.731838] add      /class/usb_endpoint/usbdev1.4_ep81 (usb_endpoint)
	UDEV  [1215983089.750717] add      /class/input/input4 (input)
	UDEV  [1215983089.770017] add      /class/input/input4/event2 (input)

This is what can be found in dmesg:

	usb 1-1: new low speed USB device using ohci_hcd and address 4
	usb 1-1: configuration #1 chosen from 1 choice
	input: Ver 1.0 USB To RS232 Interface (V1.0) BaudRate 2400bps as /class/input/input4
	input,hidraw0: USB HID v1.00 Gamepad [Ver 1.0 USB To RS232 Interface (V1.0) BaudRate 2400bps] on usb-0000:00:0f.2-1

Gamepad...? Sounds like fun.

I tried these drivers:
	megatec - no success, I couldn not find any virtual serial ports being created (like with usbserial).
	megatec_usb - just says „Megatec protocol UPS not detected.“. The corresponding files from /sys/class/input disappear when this driver is invoked...
	usbhid-ups - no fun at all: „No matching HID UPS found“

The NUT version used is 2.2.2 from an ArchLinux package. Kernel version is 2.6.25.10 (Vanilla, not the distro kernel). My distro has an entry for Unitek in udev rules:

	SYSFS{idVendor}=="0f03", SYSFS{idProduct}=="0001", MODE="664", GROUP="nut"

Vendor and product ids correspond to what lsusb sees. The whole output from lsusb -v is attached (lsusb.txt).

Is this device supported? If so, what am I doin wrong? If it is not supported yet, how could I help to make it work with NUT?

Best regards,

Andrej
