https://bugzilla.kernel.org/show_bug.cgi?id=207219 Bug ID: 207219 Summary: [BISECTED] Sony Vaio laptop built-in ricoh webcam no longer found on Fedora 31 with 5.4.11 kernel Product: Drivers Version: 2.5 Kernel Version: 5.5.15 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: USB Assignee: drivers_usb@xxxxxxxxxxxxxxxxxxxxxx Reporter: williambader@xxxxxxxxxxx Regression: No Linux no longer finds the built-in Ricoh webcam on my Sony Vaio laptop. Let me know if there is anything that I can try. Steve on RedHat's bugzilla showed me how to build kernels from source and then test patches. /var/log/messages shows the lines below, and Linux does not create /dev/video*.

Mar 30 15:00:58 scslaptop37 kernel: usb 1-1.3: can't set config #247, error -32 I did a kernel bisection and identified the 5.4.10 commit [7cbdf96cda1fbffb17ec26ea65e1fe63c9aed430] usb: missing parentheses in USE_NEW_SCHEME The change is just one line: drivers/usb/core/hub.c -#define USE_NEW_SCHEME(i, scheme) ((i) / 2 == (int)scheme) +#define USE_NEW_SCHEME(i, scheme) ((i) / 2 == (int)(scheme)) The macro is called as USE_NEW_SCHEME(retry, old_scheme_first_port || old_scheme_first || quick_enumeration) so the parentheses change it from using the new scheme to using the old scheme if old_scheme_first or quick_enumeration is set. That seems to make sense, but the change doesn't seem to work for the webcam. There is a discussion at https://bugzilla.redhat.com/show_bug.cgi?id=1818952 I tried applying the patches at https://bugzilla.kernel.org/show_bug.cgi?id=203419#c27 (testpatch that doesn't clear TT buffer after protocol STALL) but they didn't help.
