Increasing speed in interrupt tranfer

The maximum speed for the interrupt transfer for USB 2.0 full speed is 64kbytes/s. LPC2148 is used in device side. Is there a possibility of increasing the interrupt transfer speed by increasing the packet size. In that case generic device class wont support the device. Is there any possibility of moving to custom hid driver

  • Hello Westermark,
    Thanks for the reply. The problem in using bulk trnsfer is that application will be tested in the stress condition loading the PC with many other applications and it is expected to meet both guarantied data and time. Thats why the interrupt transfer was chose. So your opinion is the maximum packet size cannot be increased from 64bytes for interrupt transfer in any method? Our present scope is using usb 2.0 full speed only. Your suggession will be very helpful to me.
