virtualbox beta 3.2.0 & ZTE 4g USB modem

**Rowanmf** · May 7th, 2010

please can someone shed some light for me .

I have done a upgrade to 10.4 lucid , and i wanted to get away from dualboot , XP is used ONLY to use the ZTE tu25 4g usb modem ..so i am trying virtualbox , i had to get beta 3.2.0 as it has USB support ..

Firstly please note ubuntu sees the modem -

rowan-laptop kernel: [25210.452109] usb 2-1: new high speed USB device using ehci_hcd and address 35
May 7 22:51:47 rowan-laptop kernel: [25210.585234] usb 2-1: configuration #1 chosen from 1 choice
May 7 22:51:47 rowan-laptop kernel: [25210.585491] option 2-1:1.0: GSM modem (1-port) converter detected
May 7 22:51:47 rowan-laptop kernel: [25210.585670] usb 2-1: GSM modem (1-port) converter now attached to ttyUSB0

but does nothing with it !!

config in virtualbox sees the ZTE modem adds the filter and everything
but when in the virtualbox and i run the ZTE modem software it says no device , in the top of VB under usb the ZTE modem is seen but it's greyed out .

in groups i am a member of vboxusers ..

I am now stumped ...

i have just got a new HDD so i am gonna do a fresh 10.4 install and get back to virtualbox etc then see from there but PLEASE if you have any input please let me know .

Thanks

well i have done a fresh 10.4 install , a fresh virtualbox 3.2.0 beta , and it's still doing the same .
I can see any other usb device , no problem , but this frigging modem is driving me around the wall , the virtualbox sees the modem , but it's greyed out ..
i have now read everything in the ubuntu guide and virtualbox docs , and i have googled and read the virtualbox forum ... i am now well and trully stumped .

Any advice is welcome ..
