[Libusb-devel] Bulk transfer perfromance

[Rick L. <Ric...@mc...>]

Hello,

 

I have a couple of questions on bulk transfers.

 

1.       I have a device that scans data at various clock speeds.
Unfortunately, the device has a very small buffer. At the device's
maximum rate, the buffer fills up in 2.5 mS. I read data from the buffer
using bulk transfers. The device has a max packet size of 64 bytes. Can
I expect to read data from the device's buffer fast enough using Libusb
so that I don't lose data? (actually the device will go into an overrun
state if I don't read fast enough)

2.       Does setting the Libusb debug level to 3 impact the performance
of doing bulk transfers? I testing the throughput of my device - should
I set the debug level to 0?

Thanks
