Is there a way to reduce that or is that the absolute minimum in HS mode?
We already discussed, in this email thread earlier, why SOF interrupts
required and unmasked.
Only in case when connected device with CTRL+BLK EP's only (like flash
drive) and directly connected to cores root HUB, SOF's will be masked.
That's the setup I have on Altera SoCFPGA, yet the SOFs are still present.
Could you please send verbose lsusb on connected to dwc2 device
and driver debug log.
What exactly do you mean by this one ?
Enable debugging messages and verbose debugging messages for dwc2 from
make menuconfig. Provide dmesg starting from dwc2 load till HS device
connected to dwc2 port and enumerated.
Driver debug log not required.
Based on lsusb output: to dwc2 port connected "Standard Microsystems
Corp. USB 2.0 Hub" to which connected your HS device "SanDisk Corp.
Ultra". Because of connected HUB, which have periodic endpoint
(Interrupt IN EP1) like all HUB's, dwc2 forced in Buffer DMA mode unmask
I don't understand the last part, can you rephrase ?
What does that mean regarding the SOF question above ?
