Hi,
A reasonable setup for 116x for this driver would be ...
> isp1362-ohci isp1362-ohci0: ISP116x Memory usage:
> isp1362-ohci isp1362-ohci0: ISTL: 2 * 512: 1024
ISTL: 2 * 0 , because the driver currently does not support
iso transfers
> isp1362-ohci isp1362-ohci0: INTL: 4 * 64: 288
INTL: 0 * whatever , because 116x does not allow to set up a
buffer specific for interrupt transfers (in contrast to
1362).
> isp1362-ohci isp1362-ohci0: ATL : 28 * 64: 2016
This is ok. But in my current version (which you don't have
yet), I chop large transfers up into atl_queue.blk_size
bytes pieces. And as the amount of bytes one can transfer
during a frame is limited, I use:
ATL : 2 * 512
Note that for 116x, only the total size of the buffer of a
given type matters.

These are pointers to structs describing the transfers.
I guess c0342764 + sizeof(struct ptd_queue) == c0342784
Look at the definition of struct hc_isp1362_dev.

^^^^
You won't see transfers if HCFMINTVL is uninitialized.
