Hey folks, We have a lot of devices in our lab at work with USB ports meant to capture measurements or screenshots and whatnot. We cannot get a flash drive to consistently work on any of the devices. Some drives work with some, and not with others. Some drives don't work with any of them. Granted these are no name flash drives that have been in use for a while in our lab. For example, just today I was trying to capture data from an E4980A LCR meter, and after 6 flash drives, I wasn't able to to get any to be recognized. Does anyone have one they recommend for compatibility with test equipment like that? Also yes, the flash drives are all formatted with FAT32. That is supposed to be what's compatible according to the equipment manuals. Thanks! |

Could it be that the VUSB (5V) supplied by the test equipment is too whimpy (limited current output) ? Maybe you could try inserting a powered USB hub between the test equipment and the flash drive, and see if there are any improvements ? |

From the manual: --- Quote ---Saving to USB memory fails Some USB memory does not work on the E4980A/AL with firmware A.xx.xx. See the section on “USB interface port” in data sheet. --- End quote --- --- Quote ---USB Memory Notes Attention should be given to the following points when using a USB memory device with the E4980A/AL • Use a USB memory whose interface is USB 1.1. • Use a USB memory that is USB mass storage class compliant and formatted with FAT16 or FAT32. • Use the USB memory solely for the E4980A/AL. Otherwise, other data previously saved in the USB memory could be erased. • If you cannot save into or recall from the USB memory, use another USB memory device. • Keysight Technologies shall not be responsible for nor assume any liability for data loss in your USB memory device after using it with the E4980A/AL. --- End quote --- Sounds like they are quite aware that some USB drives won't work... |

Yes that is specifically for the E4980A, but all of our tektronix scopes have the same issue. As well as any of the other equipment I've tried to pull data from. It's always a hassle to find a drive that works with the device. Just trying to see if I can cut out some frustration in my day to day. |

Its step b) that is mostly the problem since various OSs/device manufacturers want "extras" and add things which are incompatible. |
