I want to know the maximum speed of USB HID. Is it limited at 64KB/s ?
If yes, anyway to break this limit ? Because it is too slow.
USB HID Speed ?
I find the answer by myself from web.
USB HID mode speed :
64 bytes / 1ms , So, it is 64000 bytes /s
= 64KB/s
USB Bulk mode speed :
19 packet x 64 bytes / 1ms, So, it is 1216000 bytes /s
= 1.216MB/s
(Correct me if I'm wrong)
I like mikroPascal than other compiler. But it only support HID mode.
I need speed, then I need other compiler for Bulk mode support.

Re:
Here is an MSD implementation in mikroPascal: http://www.rosseeld.be/DRO/PIC/index.htm#usb_msd.Tomy wrote:matrix,
Do you have any info or website about MSD ? Hope more people interest to write USB code for mikroPascal.
Kind regards, Dany.

USB HID Speed ?
i am using 18F4550 to communicate PC to USB.
i have used hid communication but it is too slow.
What type of class i should use for fast and reliable communication?
i am not interested to use CDC as it creats comm port of PC.
Your response will be highly appreciated.
