Re: USB/umass BBB bulk-in TIMEOUT issue

[Matthew Dillon <dillon@xxxxxxxxxxxxxxxxxxxx>]

:I hope this is the correct forum for user-type questions.

:I have the latest CVS version of DragonFly, having cvsup'ed my FreeBSD 
:4.10 to DragonFlyBSD 1.0-CURRENT. I get the umass BBB bulk-in TIMEOUT 
:error when trying to write an ISO image to my USB CD-RW. This CD-RW, and 
:a USB printer, are connected via a USB 2.0 PCI card. After getting the 
:error message, the machine reboots on its own.
:
:I have made little changes to the GENERIC kernel. I added the ehci and 
:USB_DEBUG options. (I'd like to send the output of USB_DEBUG, but where 
:is the log file?)

:Thanks for your help,

:Dmesg reports:

    It's fine.  Normally people post bugs to the bugs@ list but don't worry
    about it.

    Try ripping out 'device ehci'.  This will cause the USB2.0 ports to revert
    to USB1.1.  EHCI has known problems with a number of chipsets and should
    be considered experiemental.
