I tested the patch posted here and I cannot reproduce the bug anymore. No dmesg entries, no bad macs. http://marc.info/?l=linux-usb&m=149681741816768&w=2 Thanks, Frederik -------- Original Message -------- From: Frederik Schwan [mailto:frederik.schwan@xxxxxxxxx] Sent: Friday, Jun 9, 2017 8:38 AM CEST To: linux-usb@xxxxxxxxxxxxxxx Subject: RTL8153 connected via ASM1042A causes transfer errors > > Hi everyone, > here is a bug that occurs when a RTL8153 is connected to the host via an ASM1042A chip.
