Hi Rodolphe - you need to type lsusb
and find your USRP device ID. For instance, for my HackRF lsusb indicates it's ID is: Bus 003 Device 003: ID 1d50:6089 OpenMoko, Inc. Great Scott Gadgets HackRF One SDR Then I would type lsusb -v -d 1d50:6089 Once you have the output for you USRP device, look for the entry bcdUSB My HackRF has USB2 interface but it's plugged into a USB3 port and lsusb indicates bcdUSB 2 It the problem persists, you may have to swap out the cable - it could be a cable problem. -- Cinaed On 3/19/20 1:06 AM, Rodolphe Bertolini wrote: > Cinaed, > > Thank you. > Output is empty (except at FIXME warning : "FIXME: alloc bigger buffer > for device capability descriptors"). > However, without filtering I have something like this : > > Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub > Device Descriptor: > bLength 18 > bDescriptorType 1 > bcdUSB 3.10 > ... > bInterfaceProtocol 0 Full speed (or root) hub > > I think that this bus is USB 3.0 capable, but for some reason the > "superspeed" is not activated. > Also no information about data rate is given about this bus. > > Regards, > Rodolphe > > Le mer. 18 mars 2020 à 20:29, Cinaed Simson via USRP-users > <usrp-users@lists.ettus.com <mailto:usrp-users@lists.ettus.com>> a écrit : > > A USB3 port is SuperSpeed port. > > For a quick check, try > > lsusb -v | grep 5Gbps > > to confirm you have at least 1 working USB3 port. > > And then you can check the port speed where the device is > connected using lsusb -v. > > -- Cinaed > > > > On 3/18/20 7:36 AM, Rodolphe Bertolini via USRP-users wrote: >> Marcus, >> USB plug is rotated (from row is at top), but yes I get the exact >> same port as your. >> Thank you >> Regards, >> Rodolphe >> >> Le mer. 18 mars 2020 à 16:20, Marcus Müller via USRP-users >> <usrp-users@lists.ettus.com <mailto:usrp-users@lists.ettus.com>> >> a écrit : >> >> Hi Rodolphe, >> >> considering this is as confusing to me as to you: I took a >> picture of my >> USB3 port.
