Some USB-C/USB-A to Ethernet adapters have been known to cause issues when operating the Altos V1 sample. These incompatible adapters result in data packet loss when using the ROS Noetic (ROS1) driver on Ubuntu 20.04, which is required for operating the demo application provided with the evaluation kit. Below, we provide a list of adapters that are verified to work, as well as those that are known to be faulty. **Known good adapters:** [Anker USB-C](https://www.amazon.com/gp/product/B07S6LYNC4/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1) Model Number: A8341 [UNI - USB-A](https://www.amazon.com/gp/product/B087QFQW6F/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1) Model Number AE01 [UNI - USB-C](https://www.amazon.com/gp/product/B077KXY71Q/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1) Model Number UNICE01 [TOTU Hub USB-C](https://www.amazon.com/TOTU-Ethernet-Delivery-Portable-Laptops/dp/B07FX2LW35/ref=sr_1_4?crid=2MPB06G8IHG2Y&dib=eyJ2IjoiMSJ9.WlB8BhOOwuulyTLjuy5vI9ytZw26V_BLoqE8ntRU7mwJOD65q4Zp9cXUn1Mc_l61lElpyzrSKLA59s3zDhF7XNO8dkXYJWg0bjSElj1q5PWsRLz89xOAEtnbSkGfxh3Wj6r_sj3ezGciIvf1oDbKOsc67lVbVIRNbcr1RWYfsxoJX_56f6IL1xhgTvsDnfl1Ug4_ii5ewhzVXrC0KLRnyZemWAuVf3ZW3BqJsnQUiZs.jfYa8J0yqU_nuwKjpz_iQVL56s1BthRW2G-ZJyYsnWA&dib_tag=se&keywords=TOTU%2BHub%2BUSB-C&qid=1712277945&sprefix=totu%2Bhub%2Busb-c%2B%2Caps%2C135&sr=8-4&th=1) Model Number TT-HB001C [SAMZHE USB-C (2.5Gbps)](https://detail.tmall.com/item.htm?_u=5l3uj8268b&id=715345358717&spm=a1z09.2.0.0.485b2e8dTghKrm) Realtek Semiconductor Corp.
