Hi List,

i have here a mysterious VisionPlus from Twinhand in the usb-version. It 
has the same tuning-problem like the
PCI version which is described here:

http://www.linuxtv.org/pipermail/linux-dvb/2005-May/001802.html

The device looks like the magicbox from here:
http://www.twinhan.com/product_terrestrial_5.asp
But under the label "magicbox" (a sticker) i can read VisionPlus.

Usbview identify the device as VP7041:

The firmware file is 'dvb-usb-dibusb-5.0.0.11.fw', the correct one for 
the MagicBox1. but the line identify my device as 'Cypress AN2135'?

If i try the scan the frequenzy the "scan" program from dvb-apps returns:

------------------------------------------------------------------------

------------------------------------------------------------------------

on every transponder.

The same happends with kaffeine scanfunction.

If i try the device under win2k with the same antenna it receive 21 
channels, so the antenna is not the problem.

Can anyone help here?

regards
   AleX
