Hello.  I am new to the Amiga; owned a C128 and now seeing what I missed.  I am hoping you guys and gals can help me with an issue I am experiencing.
I bought a A500 Rev. 5 and am trying it out.  I've been reading a lot and watching YT videos for help.  I want to install a Gotek but am having issues.  I don't know if it's the A500 or something else.  I bought a Gotek from an Ebayer all ready for installing in an Amiga (just supply the USB drive), and I also bought one from Amazon.  I installed FlashFloppy 3.37 on the Amazon drive.  Both drives have OLED displays and I can browse the files both the buttons.  However, the A500 remains at the WB hand logo with no Gotek LED activity.  Both Gotek's are set to S0.  I have tried copying the FF.CFG file to the pre-installed one.  I also tried copying the HXCSDFE.CFG and AUTOBOOT.HFE files, as well as trying none of these files.  
With the Chinon FB-354 connected, the A500 will boot some Floppy games I recently bought off Ebay.  Some other disks have issues and won't load.  I am not sure how stable the computer is.  But if I can load 4-5 different games disks then it should be somewhat OK.  Curiously a Cloanto WB1.3 floppy from Ebay boots part way but then gives me read/write errors.  When I swap drives, I made sure the floppy cable's pin 1 is the same for both the real floppy and the Gotek.
I did try the pre-configured Gotek in a A1200 and it seems to work.  Could anyone tell me what else I should look at?   This is driving me crazy not being able to figure it out.  Thanks!
