Hi John,

 

I can think of a couple of things that can cause it to be limited to a slow rate:

• It is running at USB 2.0 speed, not 3.0.  That can happen if you plug into the wrong port on your machine, or if for some reason it does not negotiate USB 3 speed.
• Most USB cameras have a feature like DeviceLinkThroughputLimit.  If that got set low for some reason that would slow it down.

I have built, base-7.0.6,  areaDetectorR3-13 with ADSpinnaker master on Alma 9. I am using a FLIR BlackflyS 161S7M USB camera. This is large, 5320x3032 pixels.

 

The camera is detected but I get a "Not enough available memory to allocate buffers for streaming" error.

 

In ADSpinnakerConfig I have set numSPBuffer to minimum  = 10 (?)

 

# ADSpinnakerConfig(const char *portName, const char *cameraId, int numSPBuffers,

#                   size_t maxMemory, int priority, int stackSize)

ADSpinnakerConfig("SP1", 22671882, 10, 0, 0,0)

 

The host computer has 16G, 13.7 G free,

 

Ideas?
