Jester 24/48 USB Problems


Recommended Posts

I have a Jester 24/48 at my college that has issues with the USB port. When I try to save a show file to a usb stick it keeps saying working until I cancel the save. It also has issues using a keyboard for labelling cues and subs as it will only work with a specific keyboard as long as the keyboard was plugged in before it got turned on. It is running v3.1 firmware I have tried updating it to 4.1 but it cannot recognise the usb stick. I was just wondering if I was doing something wrong or if there is a issue with the desk.

JesterOS 4.1 can be downloaded here...

https://zero88.com/storage/downloads/248ce535-0aef-40ac-89a6-88e34e4f2cf1/Jester41.zip

Once downloaded, extract the file to the root of a USB stick, and plug into the Jester. Then boot the Jester with the left and right arrow keys held down.

If the Jester cannot detect the USB stick, turn the Jester off, and remove the USB stick. Then turn the Jester on, and go into Super User (SHIFT + MODE). Then arrow down to <USB Host>. Hold SHIFT and press ENTER, and you should see the option to choose <Upgrade>. Press this, and run the upgrade.

If you have any questions please let us know.

Thanks for the reply. When I boot it with the arrows held down it goes into the update mode but it keeps saying "Searching for an upgrade file, Please Wait". I left it for 20mins before cancelling it as it didn't seem to find the update file. the usb has a light that was just solid red the entire time if that gives any info.

 

When I go into the usb host mode option it doesn't come up with a upgrade option it just shows some text which I guess is some version info.

 

I have included photos to see if that gives you any help.

When you chose <USB Host>, did you have Shift held down?

Hi Josh,

Yes I did have the shift button held down when I pressed enter. I have tried restarting it several times to see if that helps but it made no change.

Thanks for confirming.

Please email us a picture of the console's serial number to support@zero88.com, displayed at the top of the LCD when you open Super User, and we will be able to advise the next step.

If you are able to, it would also be worth copying the Jester4.1 software onto a different USB stick if you have one to hand, and try booting the console with the left and right arrow keys held down again. 

If you have any questions let me know.

The problem is i can't save or load any show from the usb stick. Can you hep me? It's very urgent, because i start a festival next week. Thank's!

Hi Light.UP,

Which format did you format the USB drive into? Have you tried other USB drives?

Please can you use a different USB stick to perform a software update from V3.2 to V4.1?

Then perform the USB Host update, as described above (remember to press SHIFT!).

Then try loading the showfiles.

Hi, I have formatted the USB drive into FAT 32 (new USB drive i brought specially), it didn't work, so i have tested in fat 16, didn't work even. It's a 64Gb USB drive, does it make a difference? I tried the USB hist update too, didn't work!

 

What should i do?

Hello, I have done a test with 2 news usb sticks (16Gb, i didn't find smaller), it didn't work. But i've found an old 4Gb stick at home, so i'll test on Saturday when i go back to the theater. Do you have any other ideas?

Hello, I'm testing now with a 2Go USB stick, in FAT32, it still doesn't work... The USB plug seems to be OK because i use it often for a USB ledlight, so at least the USB power supply works...

 

What can i do anymore? By luck the internal memory is ok, and i have changed the battery inside last year.

Not much else that we can think of on this other than failure of something in the USB circuit itself.

Only way to tell that is have the desk back or investigation.

PM on the address below to discuss this more.
