some additional info.
this is weird: although everything is fine while using 2.0 controllers, when I use the 3.0 expansion card and the b100 gets cold-started (i mean it is not yet loaded with firmware) i get this: dc7900 utils]# ./uhd_find_devices linux; GNU C++ version 4.6.3 20120306 (Red Hat 4.6.3-2); Boost_104700; UHD_003.004.000-1-gea19de0b -- Loading firmware image: /home/soft-rf/Desktop/UHD-Mirror/UHD-images-003.004.000-f500b92/share/uhd/images/usrp_b100_fw.ihx... done No UHD Devices Found if it already has the firmware loaded, I just get: @dc7900 utils]# ./uhd_find_devices linux; GNU C++ version 4.6.3 20120306 (Red Hat 4.6.3-2); Boost_104700; UHD_003.004.000-1-gea19de0b No UHD Devices Found this also happens on a Fedora16 x86_64 machine, and standard USB-memories work well when connected to the expansion board with the NEC 3.0 controller. any clues? regards vince 2012/6/11 Ben Hilburn <b...@ettus.com>: > Vincenzo - > > I have the exact same USB 3.0 controller: > 0d:00.0 USB controller: NEC Corporation uPD720200 USB 3.0 Host Controller > (rev 04) > > ... on this Thinkpad 420s, and I have no issues using the B100. > > Like Nick said, can you provide the output of: > > $ sudo lspci -v > $ uname -a > > Also, without making any changes, if you plug the B100 into a USB2.0 port, > it works fine? > > Cheers, > Ben > > On Mon, Jun 11, 2012 at 10:39 AM, Nick Foster <n...@ettus.com> wrote: >> >> On Mon, Jun 11, 2012 at 10:28 AM, Vincenzo Pellegrini <wwvi...@gmail.com> >> wrote: >>> >>> Hi Nick and everybody, >>> >>> today I tried to access my B100 via the NEC Corporation uPD720200 >>> usb 3.0 controller that you quoted in this message: >>> >>> http://www.mail-archive.com/discuss-gnuradio@gnu.org/msg35877.html >>> >>> installed on a PCIe USB 3.0 expansion card. >>> >>> UHD could not find devices (./uhd_find_devices) >>> >>> whereas it actually can find my B100 both if it is connected to the USB >>> 2.0 >>> controller on-board the PC motherboard and if it's connected to a PCI >>> USB 2.0 expansion card. >> >> >> Mine's onboard, although it really shouldn't make a difference.
