Hi! I recently bought a USB-1208FS-Plus to send a TTL signal from my MacBook Pro (macOS Mojave) to a TMS Magstim device. I plug it in and run DaqTest (via Matlab 2020b), but it keeps saying that - “Sorry. Couldn’t find any USB-1208FS, -1408FS, or -1608FS boxes connected to your computer”. LED on the DAQ has a light, but it is not blinking at all. DaqFind function can’t recognize the DAQ as well with showing an error message - “Did not find a device, should I clear PsychHID and try again?” Have tried the obvious: unplugged/replugged quit restarted Matlab rebooted computer Previously I’ve used the same DAQ with a very old MacBook Pro (~ 2010’s model) and Matlab old version, and I didn’t have any problems using the DAQ. Any suggestions? Thanks! Taek ---

As far as this thread goes: > [@Can USB-1208FS-Plus be a substitute for USB-1208FS?](https://psychtoolbox.discourse.group/t/can-usb-1208fs-plus-be-a-substitute-for-usb-1208fs/3230): > > Hello, USB-1208FS is one of the DAQ devices compatible with PTB3, but there is also a device with a similar name, USB-1208FS-Plus. If I try to control an external input device and a LED light emitter, is it okey to use USB-1208FS-Plus instead of USB-1208FS? Or perhaps is it not possible to control USB-1208FS-Plus correctly with PBT3 functions? I am currently designing an experimental environment in a hurry, but being a novice to PTB3, I am not sure of the correct device configuration. If yo… the plus version is not compatible. Your options are to try to find the old model, or upgrade to a LabJack or Arduino to send the TTL triggers. My recent performance testing showed that using `IOPort` you can get excellent command-response times using a Seeduino Xiao: [Serial port interface code -- a performance comparison](https://psychtoolbox.discourse.group/t/serial-port-interface-code-a-performance-comparison/3781) ---

Agreed. Arduino is stupidly simple to incorporate and use! ---

Thank you @Ian-Max-Andolina I returned USB-1208FS-Plus, and re-ordered USB-1208FS. I’ve tested and confirmed that USB-1208FS is compatible with PTB3 (using MacBook Pro). I literally have no ideas why USB-1208FS-Plus does not work with PTB3, but I’m glad USB-1208FS does work. ---

Because the 1208FS-Plus needs extra work to enable it. If somebody wants to spend money on that task, see my comments on this following GitHub issue for what can and can not be done with small amounts of money and user collaboration: > > > Hello, PTB-3 supports the USB-1208FS daq and I use several. Currently, Measureme…nt computing only has USB-1208FS-plus while the regular version may be several months backorder due to COVID IC supply issues. I purchased and tested the USB-1208FS-plus but Matlab and PTB won't recognize the device unlike the original version. > I talked to their technical support and they say this is almost surely due to the software looking for a different string number for the device. > I am writing if a patch could be made to support the USB-1208FS-plus by allowing PTB-3 to search for the correct string since the USB-1208FS do not seem to be available for quite some time. > thank you
