Same MacBook Pro 13" Early 2015 and same ASMedia ASM1042A, but a different monitor (LG 34UC88-B instead of LG 34CB98= -B) and a different mouse (Logitech G403 Prodigy, 046d:c083, two interfaces bot= h at 1ms). Same issue, same workaround fixes it.

G403 Prodigy Gaming Mouse Interface 0: bInterfaceProtocol Mouse, EP 0x81 IN, bInterval 1 Interface 1: bInterfaceProtocol 0, EP 0x82 IN, bInterval 1 I also plugged in a no-name mouse (China Resource Semico, 1a2c:0043, one interface at 10ms) and it works fine without any workaround. Same controlle= r, same hub chain. The 10ms vs 1ms pattern holds here too. Interface 0: bInterfaceProtocol Mouse, EP 0x81 IN, bInterval 10 I also noticed that all mice work in the OpenCore bootloader, same as on ma= cOS and Windows. OpenCore uses the EFI USB stack, which presumably keeps the interrupt pipe active without idle logic. This fits the theory that the pro= blem is not necessarily in the ASM1042A hardware alone or in usbhid alone, but in the combination of those two. --=20 You may reply to this email to add a comment.
