 libusb is in ports, and a number of other ports use it.

 That should provide a variety of working examples.

I'm not entirely sure, but it's possible it only shows ugen devices.

Has anyone used libusb for accessing usb devices here?

2008-07-22 Thread Andrew Falanga 
Hi,

I'd like to know if anyone here on the list has ever used libusb
(http://libusb.sourceforge.net) for accessing usb devices.  I
successfully compiled and installed it on my FreeBSD 7 laptop but when
I run a test program no USB HUBs are found.  The same test on a Fedora
box works fine.  I was wondering what the magic is for FreeBSD since
the web site claims the package works on FreeBSD.

Thanks,
Andy

Well, I feel like a total bafoon.  I searched yesterday for it at
freshports.org and turned up nothing.  The reason: I was searching for
usblib rather than libusb.  How incredibly frustrating.

Thanks,
Andy

Ok, I've installed from the ports collection this time (at home now on my 
6.2p11 box) and I'm seeing busses in my computer.  However, when I plug in my 
USB thumb drive, a Sandisk Cruizer Micro that the kernel does see as da0 
(verified in /var/log/messages), I don't get any devices shown.  Below is the 
code to the program I'm using.  It's a hack of the basic example on the 
libusb.sourceforge.net website docs.

#include iostream


#include usb.h

int main(void) {
   usb_init();

   struct usb_bus *busses;

   usb_init();
   usb_find_busses();
   usb_find_devices();

   busses = usb_get_busses();
   if(busses)
  std::cout  we found some busses  std::endl;
   else
  std::cout  no busses were found  std::endl;

   struct usb_bus *bus;
   int c, i, a, bussCount(0);

   /* ... */

   for (bus = busses; bus; bus = bus-next) {
  std::cout  enumerating buss:   ++bussCount  std::endl;
  struct usb_device *dev;

  // loop through each device and display its vid pid
  for (dev = bus-devices; dev; dev = dev-next) {
 struct usb_device_descriptor* pUsbDev = dev-descriptor;

 if(pUsbDev-bDeviceClass == 0x09)
std::cout  Device is a HUB\n;
 if(pUsbDev-bDeviceClass == 0x07)
std::cout  Device is a printer:\n;
 if(pUsbDev-bDeviceClass == 0x08)
 std::cout  Device is a mass storage device:\n;
 std::cout  Device Class: 
(int)pUsbDev-bDeviceClass  std::endl;
 std::cout  VID: 
std::dec  pUsbDev-idVendor   
std::hex  pUsbDev-idVendor  std::endl;
 std::cout  PID: 
std::dec  pUsbDev-idProduct   
std::hex  pUsbDev-idProduct   std::endl;

 if(dev-num_children  0) {
struct usb_device* pChild = *(dev-children);
while(pChild) {
   std::cout  Childs device class: 
  std::dec  pChild-descriptor.bDeviceClass
   
  std::hex  pChild-descriptor.bDeviceClass
  std::endl;

   pChild = pChild-next;
}
 }
  }
   }

   return 0;
}

Any ideas why I'm not seeing any devices?

Andy
