Hello there,

theres some trouble with technisat DVBS/S2 USB HD on pandaboard.
My system: ubuntu 3.2.0-1441-omap4
media_build is installed and firmware 
dvb-usb-SkyStar_USB_HD_FW_v17_63.HEX.fw
is at /lib/firmware.

With all debugging options enabled dmesg sais the following if I remove 
the stick and
reconnect it:

[...] same as above

The device has to be handled as USB 2.0 to work correctly..
=>[ 7949.248687] usb 1-1.2.5: new high-speed USB device number 11 using 
ehci-omap
looks good, but
=> [ 7947.470428] hub 1-1.2:1.0: port 5, status 0100, change 0001, 12 Mb/s
is too slow or ?

But /usr/bin/usb-devices tells me that the device is on 480Mb/s speed..

The hub:
T:  Bus=01 Lev=02 Prnt=02 Port=01 Cnt=02 Dev#=  4 Spd=480 MxCh= 5
D:  Ver= 2.00 Cls=09(hub  ) Sub=00 Prot=02 MxPS=64 #Cfgs=  1
P:  Vendor=2101 ProdID=8500 Rev=01.06
S:  Manufacturer=Action Star
S:  Product=USB2.0 Hub
C:  #Ifs= 1 Cfg#= 1 Atr=e0 MxPwr=100mA
I:  If#= 0 Alt= 1 #EPs= 1 Cls=09(hub  ) Sub=00 Prot=02 Driver=hub

The stick:
T:  Bus=01 Lev=03 Prnt=04 Port=04 Cnt=05 Dev#= 11 Spd=480 MxCh= 0
D:  Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs=  1
P:  Vendor=14f7 ProdID=0500 Rev=00.01

S:  Product=TechniSat USB device
S:  SerialNumber=0008C9F0B853

I:  If#= 0 Alt= 1 #EPs= 3 Cls=ff(vend.) Sub=00 Prot=00 Driver=(none)

What I could do to get this working ?
I dont know where to search anymore..
