@DocHardinger Haven't tried that once specifically, but I can't think of any reason a USB 2.0 Hub won't work with the Omega. That is, as long as it's used in the design as intended by the manufacturer. Let us know how it goes!

@Kazooie yep, the USB data lines should be good to connect. Just not the 5V power

I was able to fix it. I didn't even think about my /etc/config/fstab. I had anon_mount off. With it on I can now use my USB

@nsmith do you mean having a USB-C port for the Omega's USB port? That is, not for providing power and serial port access like on the Omega2 LTE?

@crispyoz Thanks. removing postfix package resolved the issue. appreciate all the help.

@nro The power supply voltage should be 5V (+/-5%) How do the power issues present? A good place to look would be making sure enough current is supplied - the cellular modem is especially power hungry. Btw the hardware design of this product is open source, schematics and more can be found at https://github.com/OnionIoT/Omega2-LTE

@Waqas Glad to hear you solved the issue. Regarding the LTE firmware, if you install the build system then you select the LTE configuration and then you can see which packages are selected in the standard LTE build. https://docs.onion.io/omega2-docs/cross-compiling.html The article I linked relies on some packages you need to install so I think you may be able to just update the standard LTE build to suit your requirements.

@crispyoz cheers for the inspiration and cheers to you!

@Missa Happy you resolved the issue! We've updated the Troubleshooting Guide to cover this scenario as well! Let us know what you end up doing with your Tau Camera!

@JohnW said in Improving camera performance: what is the theoretical maximum frame rate for the Tau camera? Is the virtual serial port not a bottleneck? The theoretical maximum frame rate is 50fps. And the USB serial port shouldn't be a bottleneck because the bandwidth required is low. Having said that, the realistic frame rate that can be achieved depends on lots of factors, such as the sensor configuration (integration time, operation mode etc.) and available resources in the host machine (CPU, cache, RAM etc.). The practical frame rate is usually between 20 and 30 fps. On the noise filter: There is no filter running on the Tau Camera hardware or in the driver. If this is a requirement, you'll need to add it in your software.

Just wanted to follow up and say this issue was solved with the tau v0.0.4 update. I no longer have dropped frames or bad data packets. If you have these issues. I would update to the latest GitHub and update your computer make sure there are no updates waiting for your bios

Hey guys. I have the latest firmware version 0.3.2 (b233) on my Omega2 and also increased my storage using external drive, but still face the same issue. Could anyone help? )

@jmztaylor Well that's good news. I suspect your USB key probably has an issue if you cannot mount it. You could likely fix it so you could mount it by running chkdsk on a windows machine or using dostools on a *nix machine. I just add those comments for future readers of this thread, but the core issue you were having would be as I detailed above.
