Hi,
I found a problem just like in the older discussion "Question about
error from xhci-hcd",
there was a xhci error "no room on ep ring" when plugin rtl8192cu on USB3.
(it works on USB2)
After applying Larry's patch "rtlwifi: rtl8192cu: Change firmware
upload to use block writes",
I still get the same error "no room on ep ring".
But under the same compat-wireless version,
rt8712 works on USB3.
Does anyone still encounter this problem after applying this patch?
or do I miss something/patches?
BR,
Jerome

And I'm sure the function rtl_block_fw_writeN is used for firmware uploading.

This problem is in the USB system, not in the wireless driver. Keep me as a Cc,
but send mail to Sarah Sharp <[email protected]> and
[email protected]. They will tell you what debugging is needed.
The patch was an attempt to minimize the number of writes needed to upload the
firmware, but it had no effect; however, it was still a good change.
I'm confused about one statement you made. There is no rt8712 driver, but there
is one named r8712u; however, it controls a completely different device than
rtl8192cu. Do you have both devices?

Hi Larry,
thanks for your help,
and sorry for my typo,
I have one rtl8192cu and one "r8712u".
Just test 8712 to check if xhci works.
I also tried to slow down between each write during firmware upload,
and enlarge the ring size in xhci_endpoint_init(),
but it seems that the trbs in the ring are not processed and
the incoming trb is always queued till ring full.
BR,
Jerome
