So, I have both a BBW and a BBB and both devices don't have working USB... If I plug in a device, like a uftdi serial adapter, the blue light flashes briefly but then stays off... It should stay on... Are you up for helping me debug it? I'm currently testing w/ the last BEAGLEBONE snapshot located at: ftp://ftp.freebsd.org/pub/FreeBSD/snapshots/ISO-IMAGES/11.0/ I'm interested in getting USB sound working on one of these. usbconfig: # usbconfig ugen0.1: <OTG Root HUB Mentor Graphics> at usbus0, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE (0mA) ugen1.1: <OTG Root HUB Mentor Graphics> at usbus1, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE (0mA) I do know one of the ports is not host, but a user port... Not sure how to fix this, or if this is because they are sharing an image between both BBW and BBB.... # uname -a FreeBSD beaglebone 11.0-CURRENT FreeBSD 11.0-CURRENT #0 r265054: Tue Apr 29 09:45:24 UTC 2014 root@grind.freebsd.org:/usr/obj/arm.armv6/usr/src/sys/BEAGLEBONE arm relevant parts of dmesg: musbotg0: <TI AM33xx integrated USB OTG controller> mem 0x47400000-0x47400fff,0x 47401000-0x474012ff,0x47401300-0x474013ff,0x47401400-0x474017ff,0x47401800-0x474 01aff,0x47401b00-0x47401bff,0x47401c00-0x47401fff irq 17,18,19 on simplebus0 musbotg0: TI AM335X USBSS v0.0.13 usbus0: Dynamic FIFO sizing detected, assuming 16Kbytes of FIFO RAM usbus0 on musbotg0 usbus1: Dynamic FIFO sizing detected, assuming 16Kbytes of FIFO RAM usbus1 on musbotg0 [...] Timecounters tick every 10.000 msec usbus0: 480Mbps High Speed USB v2.0 usbus1: 480Mbps High Speed USB v2.0 ugen0.1: <Mentor Graphics> at usbus0 uhub0: <Mentor Graphics OTG Root HUB, class 9/0, rev 2.00/1.00, addr 1> on usbus0 ugen1.1: <Mentor Graphics> at usbus1 uhub1: <Mentor Graphics OTG Root HUB, class 9/0, rev 2.00/1.00, addr 1> on usbus1 Thanks. -- John-Mark Gurney Voice: +1 415 225 5579 "All that I will do, has been done, All that I have, has not."
