Of course not, and you won't find any.  If you insist on using Delphi,
you will have to port the code yourself.  Delphi programmers HAVE to be
adept at interfacing with C and C++ code, and porting C code to Delphi. 
That's the price of using a niche product.

The purpose of libusb is to allow you to access USB devices without
having to write your own kernel driver.  Libusb was originally written
for Linux.  Stephan Meyer was instrumental in porting it to Windows and
continues to administer the Windows port.  libusb0.dll is simply the
user-mode half of the Windows version of libusb 0.x.  (The kernel half
is in libusb0.sys.)

IIRC, Peter wants his copyright here as well.

I don't have any other comment at this time. It is time to get the 
frontend/backend specification done and then do a few implementations. 
No doubt, many issues will come up and mistakes discovered.

cheers

I have no idea what you're trying to do.  Many cell phones do present
themselves as USB devices, and the two libraries that were pointed out
earlier are designed to allow you to manipulate cell phones from
applications.  That's probably where you should start looking.

Help! usb_find_busses() error in ARM linux

Hello,

    I am developing an application to drive an usb
device on an embedded linux ARM board (AT91RM9200,
Linux 2.4.27-vrs1). I downloaded the libusb-0.1.12,
cross-compiled it in redhat-linux 9.0 (Linux 2.4.20-8)
with arm-linux-gcc 3.4.1, then download to the ARM
board, but the function call usb_find_busses() return
-2, what is the meaning of the error code -2? Please
help, thank you very much.

Best regards, 
Daly

$ perror 2
OS error code   2:  No such file or directory

(perror comes with MySQL, but perror() is also a system call.)

Does the 2.4.27 kernel includes support for the AT91RM9200's USB host?
It's OHCI, so the usb-ohci module should be able to do it, but somehow
you'll have to tell it what address to use.

Re: Help! usb_find_busses() error in ARM linux

Hi Peter,

   Thanks for your reply.
   I could not found the file /proc/bus/usb/devices,
why? It works in Redhat 9.0. 
   How to make it work? Thank you.
