HI TI Support team,
客户咨询如下问题：
产品内置了 TUSB4020BIP ，再把USB转TTL，但是假如此时有一个行为长时间把 TUSB4020BIP 的USB的D+/-短接在一起，这种行为是否会存在损坏 TUSB4020BIP的风险呢，假如我又把短接的行为去掉了，再去使用 TUSB4020BIP的USB2.0的相关功能，此时是否会出现无法识别USB的情况呢？
TUSB4020BIP is built into the product, and then USB is converted to TTL, but if there is a behavior at this time to short-circuit the USB D+/- of TUSB4020BIP for a long time, will this behavior have the risk of damage to TUSB4020BIP? If I remove the short-circuit behavior, To use TUSB4020BIP USB2.0 related functions, at this time will not be able to identify the USB situation?
