blade USB3.0 problem

[andrew77]

Hello

I have the following problem:
I have a dual boot Windows 10 /ubuntu 14.04 LTS on my HP250G4 laptop;
in order to make my bladeRFX40 work on ubuntu as Superspeed usb3.0 I have first to start pc into windows and then reboot to ubuntu: in this way my bladeRF is recognized as SuperSpeed; otherwise (If I start my pc directly into ubuntu without pasing by windows) is recognized as HighSpeed. (the blade is attached into the same usb3.0 port)
I don't have any software or driver to make my balde work on windows, all my software are on ubuntu.
This is the usb-devices when the blade works as usb2.0:

T: Bus=01 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 8 Spd=480 MxCh= 0
D: Ver= 2.10 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1
P: Vendor=1d50 ProdID=6066 Rev=00.00
S: Manufacturer=Nuand
S: Product=bladeRF
S: SerialNumber=c36781bf545973547fdfed05e6edd3a7
C: #Ifs= 1 Cfg#= 1 Atr=80 MxPwr=200mA
I: If#= 0 Alt= 0 #EPs= 0 Cls=ff(vend.) Sub=00 Prot=00 Driver=(none

Instead, when blade works as SUPERspeed USB3.0 this is the result uf usb-devices:

T: Bus=02 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 2 Spd=5000 MxCh= 0
D: Ver= 3.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS= 9 #Cfgs= 1
P: Vendor=1d50 ProdID=6066 Rev=00.00
S: Manufacturer=Nuand
S: Product=bladeRF
S: SerialNumber=c36781bf545973547fdfed05e6edd3a7
C: #Ifs= 1 Cfg#= 1 Atr=80 MxPwr=800mA
I: If#= 0 Alt= 0 #EPs= 0 Cls=ff(vend.) Sub=00 Prot=00 Driver=(none)

Any help is highly appreciated
thanks

It's because of the cable provided from NUAND !!!

With another cable it works perfectly!!

Hello John
The question is yet to be solved:
The original cable is a black cable from "Cable Matters" ,
This morning I tested other two cables (shorter) and worked at SuperSpeed (OK), so I tested again the black cable and worked at High-Speed; this afternoon I bought a blue cable (1,5 mt long) and tested before buying it: ok (Superspeed)
Once bought, I tested this new blue cable at home and Surprise! doesn't work! -> HighSpeed!!!

Now What I can suppose??
The USB3 connector on the board doesn't mate or some contact is broken?


So I cleaned the USB3 connector on the board with a "contact cleaner" and now the blue cable works...

Ok Jon

I've just checked the soldering of it, it is ok
It is a micro type b

Now I suppose It was a dirty contact
thanks
