If Ramya can send patches against the driver and USB > core to reproduce this, then I can help. As I said in my previous email, I cannot see more than 63 sglist entries when TRBS_PER_SEGMENT is 64. I cannot see more than 127 sglist entries when TRBS_PER_SEGMENT is 128. Today, I have tested usb mass storage driver with xhci-large-tx branch for TRBS_PER_SEGMENT 64 and 128. Still, in both the cases, I am unable to do large transfers consistently when max_sectors is set to 960 (when I use USB3.0 cable. Things seem to be fine when I use USB2.0 cable). The log files are around 7 MB and 4 MB after compression. I do not think we can attach that here because of the file size. So, I will send them to you separately. Please let me know If you need any additional inputs.
