Public bug reported: [Impact] USB Storage based Realtek card reader doesn't work, because the usb-storage module tries to use it in UAS mode instead of using "ums-realtek".
[Fix] Add new IDs to ums-realtek driver. In addition to that, we add a new module knob, "enable_mmc=", to enable/disable MMC, as vendors may not pay MMC royalties. "enable_mmc" defaults to 1. [Test] After applying the patch, the card reader works, and verified "enable_mmc=" can enable/disable MMC support. [Regression Potential] Minimal. This SRU enables two specific card readers that don't work as UAS, the new module knob only introduces new behavior when enable_mmc=0. ** Affects: hwe-next Importance: Undecided Status: New ** Affects: linux (Ubuntu) Importance: Undecided Status: Incomplete ** Tags: originate-from-1800986 stella -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1806335 Title: Enable new Realtek card reader To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1806335/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
