So I made a pretty extended list of with the status and  fixes that they need. For some, I wasn’t sure how to summarize them aside from actually saying what needed to be done for each one.


The format is Name: Type of Fixes (Description of fixes) – Size of


Drivers without a TODO:

Without Maintainer:

I don’t know where these drivers are going; there aren’t any maintainers or a TODO to reference to.

csr (largest) – cxt1e1 – et131x – goldfish – line6 – octeon – phison (hasn’t been updated in over a year) – quickstart – rtl8192u –  sb105x – serqt_usb2 – slicoss – wlan-ng – zram -zsmalloc

With Maintainer:

dwc2 – usbip – vme


Drivers with a TODO without a maintainer:

May need more fixes than mentioned.

  • dgrp: minor fixes (use configfs for config stuff, dgrp_send() and dgrp_receive() could use some refactoring, shouldn’t automatically create CHAN_MAX (64) channel array entries for every device as many devices are going to have much less than 64 channels, the locking needs to be checked, check Kconfig dependencies) – 30.4KB

  • fwserial: major fixes (implement retries for RCODE_BUSY, RCODE_NO_ACK and RCODE_SEND_ERROR, implement _robust_ console on top of this, expose means of controlling attach/detach of peers via sysfs), minor fixes (unregistered vendor id can be a define in firewire.h)- 1.2KB

  • gdm72xx: minor fixes (replace kernel_thread with kthread in gdm_usb.c, replace hard-coded firmware paths with request_firmware in sdio_boot.c and usb_boot.c, clean up coding style to meet kernel standard)- 11.5KB

  • rts5139: major fixes (support more USB card reader of Realtek family, use kernel coding style, fixes, stop having thousands of lines of code duplicated with staging/rts_pstor, this driver contains an entire SD/MMC stack — it should use the stack in drivers/mmc instead; see drivers/mmc/host/ushc.c as an example, this driver presents cards as SCSI devices, but they should be MMC devices) – 42.1KB

  • silicom: minor fixes ( cleanups, locking audit, single module with all functionality, userland, fix monolithic build) – 56.8KB


(Almost) Ready to be Reviewed:

  • echo: send to lkml for review – 4KB

  • frontier: Almost ready, minor fixes (sparse clean, fix userspace interface to be sane, possibly just port to userspace with libusb), review by the USB developer community – 3.5KB

  • keucr: minor fixes (smcommon.h & smilsub.c: use kernel hweight8(), hweight16(), determine if the driver should not be using a duplicate version of the usb-storage scsi interface code, but should be merged into the drivers/usb/storage/ directory and infrastructure instead) Review by the USB developer community – 197.9KB

  • ozwpan: minor fixes (convert event tracing code to in-kernel tracing infrastructure, check for remaining ioctl & check if that can be converted into sysfs entries, convert debug prints to appropriate dev_debug or something better, modify Kconfig to add CONFIG option for enabling/disabling event tracing, check USB HCD implementation is complete and correct, testing with as many devices as possible.) Code review by USB developer community. – 8KB
