next in thread | raw e-mail | index | archive | help
I just noticed today your call from a couple of months ago to try the new umass
driver; just did so and noticed only a 2-3% improvement. the sys and int times
were all over the map so couldn't tell what to say about them. (likely from
running X doing all this :-)
The problem removing active umass devices applies to *all* usb that have
secondary drivers, though I presume you all know about that... umodem, uftdi,
uplcom all panic on removal if the secondary device is open. I presume this is
due to a lack of callbacks into the secondary driver to cause it to clean up
before the lower-level driver does. Unfortunately I don't know what the
inter-layer linkages look like and don't at the moment have much time to look
into it. (the worst one of these is my verizon card which adds yet another
extra layer - the usb ohci is a cardbus device...) (and it used to panic
whether or not the tty layer was open; something (probably newbus and the
bus-dma stuff) fixed that). Also I haven't seen anything about this on the
mailing list for the last month or so. At least the new driver works.
I also have problems with data transfers on libusb+ugen, on every device I have
that needs libusb; this includes two cameras, a scanner, and a tripp-lite ups.
The device opens properly but transfers either time out or fail. I don't know
if the new structure is likely to help there... (btw this happens on 3
different computers with totally different I/O structures; this laptop, whose
dmesg appears below, one with an Intel 865 board, and a soekris (on which I've
only tried the ups...)
UMASS works fine with one of the cameras, so I think this is a fbsd-side problem.
