Hi, Manolo!

I know reason of your problem.
I use the same configuration (Blackfin, ISP1761 and WiFI ZyXEL G202 EE with
zd1211rw driver) and
got the same error "intr period 1 uframes".
Other device: USB to Ethernet converter ADMtek ADM8515 gives the same error.
(see my bug report:
http://sourceforge.net/tracker/index.php?func=detail&aid=2485364&group_id=168333&atid=846408
)
This bug presents also in PCI driver. Therefore it is bug of isp1761 driver,
but not zd1211rw.
So I hope this bug will fixed by USB driver author.

Regards,
Oleg.
