Hi,
I'm using v2.4.18 (Slackware 8.1) and usb-uhci.
I'm wondering if the standard USB control commands are already handled by the
USB core. Most Linux usb drivers only handle vendor-specific commands (some
don't even have ioctl functions). I'd just like to verify this.
Thanks.
- Ronald

Hi,
Thanks for all the feedback I got. Actually I have to load joydev with "modprobe
joydev", then "cat /dev/js0" will show the activities on my game pad.
Now I have another problem, how can I generate the module? I tried to use "make
menuconfig" picking "Module" option for "joystick" under "in

Hi,
I'm starting to become convinced that flaky as the transport driver may

Anyway I'm still getting intermittent problems with talking to the

Hi,
I am using RH8.0, the kernel should 2.4. If I used "BuildIn" option,
the joydev.o will be generated under linux/drivers/input. If I used
"Module" option, there is no joydev.o generated. I just wonder the
compiler may put it somewhere else.
In addition, I generated the joydev.o using "Build

You were absolutely right. My usb disk is working
I'm writing about this because Matt Dharm ran across some problems a few
months back and posted a message about it on the usb-storage development
list, and my own delving into the details of scatter-gather operations
have yielded some new information.
Most of the scatter-gather buffers passed to u

However, it's simple to detect, and I suspect usb-storage should
probably add a test to make sure incoming scatterlists are ok.
Something like:
for (i = 0; i < (sg_len - 1); i++) {
if ((sg[i].length % ep_maxpa
2. This isn't really the storage drivers problem. It should be solved
at a higher layer
So, if you need to do something in storage about it, choose the simple
solution and use a large bounce buffer.
That's a good rationale. (Although the fix would go into the
scatter-gather library which belong

Hi All,
I didn't know where to post this bug so I'm posting it here. Apologies
in advance if this is not the appropriate forum or if you're already
aware of this bug.

High speed isochronous URB submits fail w -EMSGSIZE when packet
size is 1024 bytes (which is permitted by the USB 2.0 EHCI Sted).

RH 8.0 shipped with 2.4.18 plus some vendor modifications/patches.
Maybe someone who is using RH 8.0 can test this and

The "no partial packets
in the middle of an sglist" policy belongs to usb-storage..
Does it really? It seems to me that anyone doing a bulk transfer using an
s-g list would want to make it look like a single stream, i.e., no short
packets in the middle. That's built into the USB st
