Subject: [usb] Support for EPiC-based io_edgeport devices
Message-id: 46AE23FC.8010807@redhat.com
O-Subject: [RHEL5.2 PATCH] Support for EPiC-based io_edgeport devices
Bugzilla: 249760
Bugzilla #249760:
A number of EPiC-based usb to db9 serial adapters driven by the
io_edgeport driver don't function entirely correctly in RHEL5, if they
even function at all. I have one such device that mostly works, but
spews the following on the console:
--
usb 1-1: error in getting manufacturer descriptor
usb 1-1: error in getting boot descriptor
drivers/usb/serial/io_edgeport.c: edge_startup - Device Reported 0
serial ports
vs core thinking we have 2 ports, email greg@kroah.com this info.
usb 1-1: sram_write failed (ff, 0, 6)
usb 1-1: rom_write railed (ff, 0, 6)
--
Support already exists upstream though, so I took a crack at backporting
the needed changes to RHEL5 -- a nice break from all the ia64 xen
stuff... ;) Code compiles atop 2.6.18-36.el5, doesn't trigger any errors
from kabitool/kabicheck during build, and does indeed work properly with
the device that previously spat out the above errors. Output with
patched driver:
--
io_edgeport 1-2:1.0: Edgeport 2 port adapter converter detected
usb 1-2: Inside Out Networks Edgeport/2w detected
usb 1-2: Edgeport 2 port adapter converter now attached to ttyUSB0
usb 1-2: Edgeport 2 port adapter converter now attached to ttyUSB1
usbcore: registered new driver io_edgeport
drivers/usb/serial/io_edgeport.c: Edgeport USB Serial Driver v2.7
--
Note that the patch carries a number of additions to
include/linux/usb.h, only some of which are needed by the driver, but I
simply pulled the entire block of static inline function declarations
that included the needed ones from upstream. Dunno if this is approach
or only cherry-picking is a better approach here.
I also pulled in the upstream changes to deal with CmdUrbs atomically,
which is not absolutely necessary to support the additional devices, but
I presume the change was made upstream for a reason, so it seemed like a
good idea bring it along as well.
Comments/criticism/ack/nak all welcomed... :)
