Hi,
I'm new in the list and I'm having a little bit trouble to put the
megatec_usb to work.
I've been using NUT for a while with the apc and megatec driver (serial),
with no problem.
The server is a Ubuntu 8.04.2 with NUT version 2.2.1-2.1ubuntu7.2, the
default package version in this ubuntu release.
I've configured the ups.conf as follows:
[sms]
driver = megatec_usb
port = auto
desc = "Servidor Dados"
But when I run /var/lib/megatec_usb -a sms it says that "No supported
devices found"
root at comserver:/lib/nut# /lib/nut/megatec_usb -a sms

No supported devices found. Please check your device availability with
'lsusb'
and make sure you have an up-to-date version of NUT. If this does not help,
try running the driver with at least 'vendorid' and 'subdriver'
options
specified. Please refer to the man page for details about these options
(man 8 megatec_usb).
Please report your results to the NUT user's mailing list
<nut-upsuser at lists.alioth.debian.org>.
My device is connected in the bus 001, device 004, and when i do a lsusb -s
001:004 -vvv the result is as follows:
Bus 001 Device 004: ID 04b4:5500 Cypress Semiconductor Corp. HID->COM RS232

Anybody knows how to handle this?
The device is a SMS Manger III Senoidal with a USB (by the output of lsusb I
understand that it has a converter to RS232).
Any help would be appreciated.
Thanks in advance.
Gabriel.

I think that I will probably need to alter something in the megatec_usb.c so
tath it acodamodates the ew driver.

Usually this means that it will create a /dev/ttyUSBx port for you when you connect it. You can use the megatec driver to connect to this port.

Citeren Gabriel Hahmann <gabriel.hahmann at gmail.com>:> I've sniffed the usb with usbsnoop and attached in this message, where > is the best place to post this to get any help, users or development?For a trimmed down version, the nut-upsdev mailinglist would be appropriate (note there is a 40kb limit on attachments). But I think posting a link where it can be downloaded would be better (to prevent flooding the mailinglist with lots of data that most people wouldn't use anyway). In all honesty, I don't think this would bring you any further though. The attached log doesn't really show much protocol information (if any). It looks like some kind of contact closure interface, for which the genericups driver would be the right driver. But given the total lack of model detection with such an interface, choosing which type is likely going to be difficult (if possible at all). If you really want this UPS to be supported, you'd need to have the protocol specifications that is used. Otherwise, there is little hope for this device to be supported and you'd better look for a supported one. Best regards, Arjen -- Please keep list traffic on the list
