Hello. I recently upgraded from Ubuntu Maverick to Natty and hence upgraded nut from 2.4.3-1ubuntu5 to 2.6.0-1ubuntu3. My Sven PowerPro+ 1000 UPS ( http://en.sven.ru/catalog/ups/power_pro_plus_1000.htm ) worked fine with the previous version, using megatec_usb driver, but doesn't work with the current version, since megatec_usb is no longer available.
Here is the output from blazer_usb. sudo /lib/nut/blazer_usb -a sven1 -DDD Network UPS Tools - Megatec/Q1 protocol USB driver 0.03 (2.4.3) 0.000000 debug level is '3' 0.251050 Checking device (FFFF/0000) (009/002) 0.295442 - VendorID: ffff 0.295451 - ProductID: 0000 0.295456 - Manufacturer: 0.295460 - Product: 010937 0.295464 - Serial Number: 0.295468 - Bus: 009 0.295472 Trying to match device 0.295477 Device matches 0.295493 failed to claim USB device: could not claim interface 0: Device or resource busy 0.295505 detached kernel driver from USB device... 0.301458 Trying megatec protocol... 0.301466 send: Q1 0.549441 blazer_status: short reply 0.549453 Status read 1 failed 0.549458 send: Q1 1.042431 blazer_status: short reply 1.042444 Status read 2 failed 1.042449 send: Q1 1.291425 blazer_status: short reply 1.291435 Status read 3 failed 1.291440 Trying mustek protocol... 1.291445 send: QS 1.291449 read: QS 1.291453 blazer_status: short reply 1.291457 Status read 1 failed 1.291460 send: QS 1.291464 read: QS 1.291467 blazer_status: short reply 1.291470 Status read 2 failed 1.291473 send: QS 1.291476 read: QS 1.291479 blazer_status: short reply 1.291482 Status read 3 failed 1.291486 Trying megatec/old protocol... 1.291489 send: D 1.291492 read: D 1.291495 blazer_status: short reply 1.291498 Status read 1 failed 1.291502 send: D 1.291505 read: D 1.291508 blazer_status: short reply 1.291511 Status read 2 failed 1.291514 send: D 1.291517 read: D 1.291520 blazer_status: short reply 1.291524 Status read 3 failed 1.291527 No supported UPS detected I downgraded back to 2.4.3, configured nut to use megatec_usb again, and it started working again. However, it seems strange that I cannot use the latest version. -- Vlad
