USB HID problems on DC01 - read for WORK-AROUND

I just realized, that the module tree is missing the necessary HID support. I will add this next week. So don't be alarmed, when your HID connected weather stations do not show up.

Update: It turns out that the USB kernel drivers for oxnas chipset in DC01 do not support USB 1.x low speed USB HID devices. As I don't know if/how to patch these linux kernel drivers, I recommend to use a passive, cheap USB 2.0 HUB to be placed between DC01 USB port and the USB cable of the weather station. Any USB 2.0 hub for a couple of dollars will do.

Yes, I have connected a WDE1 and a TFA Nexus through one (powered) 4 port USB hub

Again Problem with DC01 and OAK Sensor. I try a second USB Hub same problems after a view days.
Here is log file:
logger (15.12.2012 22:32:47): data logger (version 4.9r, build 1203) started.
logger (15.12.2012 22:32:48): station 0 (ISS direct), can't open device /dev/ttyUSB0: No such file or directory
logger (15.12.2012 22:32:48): connect station 1 (OAK Baro via USB HID).
logger (15.12.2012 22:36:11): station 0 (ISS direct), adapter is version "1.0".
logger (15.12.2012 22:36:11): connect station 0 (ISS direct via USB serial).
logger (15.12.2012 22:40:17): no data synchronization with station 1 (OAK Baro) for 450 seconds, data logger will be restarted.
logger (15.12.2012 22:40:17): disconnect station 0 (ISS direct).
logger (15.12.2012 22:40:17): disconnect station 1 (OAK Baro).

Please use physical device descriptors "/dev/ttYMHxyz" instead of "/dev/ttyUSBx"
because enumeration of devices is randowm and can change after a reboot or reconnect.
As direct connect kit uses USB2.0 chips (as far as I know) and the OAK sensors are
also USB 2.0 I guess you won't even need a hub (only if you need more USB ports).

This has nothing to do with DC01 USB 1.x / 2.0 issues discussed in this thread.

Question: We had a brief power outage in my area on 3 January 2013. The Meteohub did not reboot after the outage (I discovered it by noting that nothing had updated to the Weather Underground for a couple of hours), and only after I had deleted the station and reentered all the settings did the station resume normal uploads of data. Do you think switching to the "/dev/ttYMHxyz" will resolve this problem? I don't recollect it happening prior to the 4.9r update, but I could misremember....

Thanks for any advise/commentary.
