Read data from usb
-
Hi! I need to read data from usb. for this purpose I have downloaded snoopPRo for packet sniffing . I got a log file but this file does not tell me anything. there are several functions such as GET_DESCRIPTOR_FROM_DEVICE , CONTROL_TRANSFER , SELECT_CONFIGURATION, BULK_OR_INTERRUPT_TRANSFER, CLASS_INTERFACE... could you help me how can I benefit from this log file?

It depends on what problem you are trying to solve. Packet sniffers sometimes have filter options to allow you to reduce the amount of low level protocol information and highlight the actual data that you are interested in. The documentation often has information that may help.

I would like to get data measurement results from the blood pressure meter which has a usb gateway. It has software to list values in txt format. but what I need to do is read data directly from the usb.

I don't see why you want to make it so difficult for yourself. However, if this is the route you decide on then you will need to get hold of the technical documentation for your BP device to decode its output.
