When we change rx_urb_size in the host side and keep it same as the QMAP related QMI, this issue is "fixed". I also checked some old commit which related with rx_urb_size, let's say= =20 https://patchwork.kernel.org/project/linux-usb/patch/20200803065105.8997-1-= yzc666@netease.com/ and https://patchwork.ozlabs.org/project/netdev/patch/20200909091302.20992-1-dn= lplm@gmail.com/#2524381. They tried to update the rx_urb_size to make QMAP works better. But these commits seems have been rejected. So do we have any new solutions or workarounds about changing the rx_urb_size? --=20 You may reply to this email to add a comment.
