Re: USB isolator, PicoScope 6 crash

@Benno: Yep, the advertisement around the specs is confusing, who’d think it might be done deliberately? USB 2.0, as I understand, requires better cable quality for the possibility of High Speed transmission (but also allows 5m instead of 3m). So saying “USB 2.0, Full Speed only” may translate to “b...

Re: Password Change, and Scope looses link

Hi Newtonez, Two questions = one answer + more questions :mrgreen: When logged in, on top of page, just above the line “It is currently Fri …”, on the left hand side, below the “Board Index” there is a link “User Control Panel”. It may depend on your browser, but with my OS X + Safari it is nearly i...

Re: USB isolator, PicoScope 6 crash

Re: Murata isolator module @PicoPilot: “... a passthrough for the external 5V power to supply the device ...” Nah, the “external power” is on the upstream side and must be connected to host GND / reference, to supply the (active) pull ups for the data lines. So the voltage must be 5V (4.6 to 5.25). ...

Re: USB isolator, PicoScope 6 crash

Hi PicoPilot, No, I didn’t supply the PicoScope by 12V! The PicoScope 5v supply is always taken from the USB connection (cable) and must be provided by the upstream USB port, called “host” (versus the PicoScope being called the “device”). USB data and power (supply for the PicoScope) must have ident...

Re: USB isolator, PicoScope 6 crash

@ PicoPilot: Thanks for the Intona hint, I found that, too. However, I’m afraid it won’t work with my PicoScope (2205) because of the limited device supply (300mA “nominal”), there is no option for an external supply, that’s bad. It seems the scope is really power hungry, esp. when switching range, ...

Re: USB isolator, PicoScope 6 crash

OMG! :oops: Thanks for your replies, Hitesh and bennog! Yes, I’m using the original blue USB cable from the USB isolator to the scope. The (cheap) isolator is from Olimex, capable to deliver 750 mA when using an external power supply (I have tried both, a wall plug 12V / 1A and a 12V lead battery to...

USB isolator, PicoScope 6 crash

Hi, I’ve sent a bug report via “Send Feedback” but didn’t receive any confirmation so far, not sure if you got it. My problem is nearly identical in PicoScope 6.6.50.3 (Win) and 6.11.8.11 (OS X): When I force the USB - connection (to my 2205) to go down to USB 2.0 Full Speed the scope basically work...
