[linux-usb-devel] [PATCH 2.4.32-pre1] ftdi_sio: Add support for FT2232C chip
Hi,
FTDI have a patched version of the ftdi_sio driver on their web-site
with support for their FT2232C chip. This was produced by Steven Turner
of FTDI. The changes have previously been incorporated into 2.6.9 with
some minor modifications and corrections. The attached patch
incorporates the changes into the 2.4 kernel, again with some minor
modifications and corrections. I also added a static array to map the
chip type to a chip name (as previously done in 2.6.12) as this is a
good point to do this and I didn't think it was worth the effort of
using a separate patch.
Signed off by me in the attachment. Please apply. TIA.

[linux-usb-devel] Proposed patch for NForce USB EHCI controllers with large memory systems
After investigating reports of large memory issues with nForce EHCI
controllers, NVIDIA has determined that EHCI data structures mapped
above 2GB in memory will cause undefined behavior in USB2 devices. The
symptoms may include system and device crashes. The data structures
which will lead to this system behavior are all Transfer Descriptors
used to control transfers on the USB2 bus. They are namely the
Isochronous Transaction Descriptors (iTD) and Split-transaction
Isochronous Transfer Descriptors (siTD) used in the periodic schedule;
and Queue Heads (QH) used in the periodic and asynchronous schedules.
Note that data buffers, Queue Element Transfer Descriptors (qTD), Frame
Span Traversal Nodes (FSTN) and the Periodic Frame List are not affected
by this restriction.
We would request that this patch be included.
If you have any questions, please feel free to e-mail me.

Darn, this is very unfortunate, because I saw some bizarre problems on
HP Viper platform with regular storage transfers (over Bulk transport).
But obviously that cannot be it. Oh well. I'll keep looking.

Looks good, but the patch was line-wrapped. How about this (with retval

[linux-usb-devel] about usb driver question
I'm sorry to disturb you again. The writer in usb-skeleton.c use devfs_register funcation to creat a device node providing user access usb device. I want to creat device node using register_chrdev function, if I don't use devfs_register funcation. In the case,I have a error message when I write register_chrdev(180,usb,fops). Because 180 major number is usb,I can't get the 180 major number again. In another case,I try to write register_chrdev(0,usb,fops),then get major number 254 from usb core.I type mknod /dev/usb/test c 254 0 in command line to creat a device node in /dev/usb/. Worryingly,usb core tell me have not such device,when I type cat /dev/usb/test in command line. WHY.. I want to let read_skel function in usb-skeleton.c operate when I type cat /dev/usb/test in command line. How can I to do if I don't use devfs_register to creat device node. Please help me I am grateful to you. --- SF.Net email is sponsored by: Discover Easy Linux Migration Strategies from IBM.

I just got back from 10 days away from email.
