Thanks again - learning something new every day as I was not aware of the esp_rom_delay_us() function; also I thought that the timestamps reflected when the operation occurred and not just when it was printed.
Therefore I'm going to not worry about the timestamps.
I'll stop this thread here and see ...

Thank you both for your advice.
I'm 'guilty as charged' with regard to thinking that it is better to pin the USB and 'processing' tasks to different cores - I didn't realise that freeRTOS is smart enough to swap things around even in mid operation.
As for the "10ms task switching" comment, it is ...

I'm using ESP-IDF V5.5.2 on a Seeed Studio Xiao ESP32S3 running at 160MHz with 8MB of octal PSRAM running at 40MHz.
What I am trying to do is to read 60ksps from a USB device using the USB Host software.
I have set up a freeRTOS task for the USB Host software and within that I set up 4 consecutive ...

I'm using ESP-IDF V5.5.2 and the USB host on an ESP32S3.
I have the DEV_MAX_COUNT #define set to 4.
Using software based on the various C code examples, I can attach a USB device, using tt and then detach the device.
I can then attach it again, use it and detach it.
When I attach it fore the 3rd ...

Looks like it was me doing something wrong.
I put in a router between the OTA server and client and it is now working OK.
(Perhaps a bit slow - might experiment with the size of the transfer packets.)

I am using ESP_IDF V5.5 and a ESP32C6 as the target device and an ESP32H2 as the OTA server. (Not sure it matters but the coordinator is a SkyConnect V1.0 dongle connected to my Home Assistant.)
I have programmed the ESP32C6 directly from my computer (iMac M1 running the latest OS, and VS Code V1 ...

Sadly no.
I also found that the Home Assistant 'Zigbee Home Automation (ZHA) only supported a small subset of the Zigbee standard and that even adding the ZHA 'quirks' could not get around this.
Therefore I dropped this for now - perhaps I'll find another way to get the connection that I want.

Environment: ESP32-H2 DEvKitM-1 V1.2; latest ESP-IDF and Zigbee library.

Using the HA_ON_OFF_LIGHT as the basis with a temperature measurement attribute and cluster added (to endpoint 2), I can connect to the coordinator successfully and it sees the switch and temperature value.

If I regularly ...

Bumping this so it does not get lost in the other unanswered questions

I have an ESP32-H2-DevKitM-1 and the Espressif IDF (V1.6.5) installed on VS Code. Using that I did an 'express' setup about 3 days ago so I should have the latest versions of the SDK etc.
I have tried to use the 'HA_ON_OFF_LIGHT" example code (unaltered in all key aspects) to connect to my "Home ...
