Hi
It seems that when sending SCSI commands over USB, the kernel doesn't
necessary build a sense response. For instance, when sending REQUEST
SENSE over ehci, the scsi_cmnd->sense_buffer is left NULL; if I run the
same REQUEST SENSE command over a direct SCSI connect, the kernel builds
the sc
Hi there -
finally I prepared a patch for the famous ftdi_sio usb serial driver.
Adding two Tagsys RFID readers I am using.
After having asked Bill Ryder he suggested adressing the
linux-usb-devel mailing list. (what?)
Sorry for the mess below - I am not doing this frequently - being
rather a lee

Hello,
I am a total newbie in Linux kernel development (but not in C
programming), and I started to write a USB driver for the DualShock 4
(and also others controllers/equipments for the PlayStation 3/4 while
I'm at it).
My objective is to sanitize what is reported to the userspace (most
games do

It is not the controllers that are particularly "buggy" here.
But rather the drivers and design

Yeah, this is all stuff that checkpatch ignores.

Hello,
I applied these along with the reverting :
xhci: Set scatter-gather limit to avoid failed block writes.
usb: xhci: Link TRB must not occur within a USB payload burst
to Linus' tree.
The excellent news is that my system no longer hard freezes with an

Allow the scheduler to select the best CPU to handle hub initalization
and LED blinking work. This extends idle residency times on idle CPUs
and conserves power.
This functionality is enabled when CONFIG_WQ_POWER_EFFICIENT is selected.
