Dear all,
The first question:
my bulkin endpoint's wMaxPacketSize is 0x0200,
but, when I call GetPipeProperties function to get maxPacketSize,but maxPacketSize is 0x40. Why?
kr2 = (*intf)->GetPipeProperties(intf, pipeRef, &direction, &number, &transferType,
&maxPacketSize, &interval);
The Second question:
I use ReadPipeAsync or ReadPipe function to get my scanner device's status,but the device is
not response.Why?
the error code is 0xe00002ed.
the Third question;
why use SWAPWORD? or when
best regards.
Thanks!
