Hello, I have a similar problem with Transcend 16GB USB flash. When the flash is plugged, FreeBSD attache it, but reports very big capacity and can not read/write it. UQ_MSC_NO_INQUIRY makes jobs in my machines. 10-current and 8-stable have same problem, and 9-stable is not tested.

It is the SCSI/CAM layer which queries over SCSI USB how big the disk is. BTW: dec2hex(17454747090944) ans = FE000000000 So it looks like some additional bits have sneaked in there? dec2hex(32463912960) ans = 78F000000 0xFE000000000 / 0x78F000000 ans = 537.67 So it looks like the mediasize was multiplied by 512 when it shouldn't. --HPS _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-usb To unsubscribe, send any mail to "freebsd-usb-unsubscr...@freebsd.org"
