Re: [Em28xx] ehci_hcd map_single: unable to map unsafe buffer on a standard NSLU2

Hi Thierry,

since you're playing around with DVB...

em2880-dvb.c:

#define EM2880_DVB_MAX_PACKETSIZE 564
#define EM2880_DVB_NUM_PACKETS 64
#define EM2880_URB_COUNT 32

try to adjust the urb count or in general those values (except PACKETSIZE)

so that was the last thing for now I'm off to denmark till sunday evening :-)
